Asynchronious foo_httpcontrol template
https://github.com/regorxxx/ajquery-xxx

*** Requirements

	This template is developed to be used in modern desktop browsers and 
	is fully compatible with Opera 10, Google Chrome 4 and Firefox 3.5.
	Internet Exploder 8 seems to work as well.

	Some other browsers might also work, but you never know until you try.

	foobar2000 1.4+ and foo_httpcontrol 0.97.25.

	Spider Monkey Panel (SMP) is not required but strongly recommended to get
	some advanced features working (allows running SMP menus via cmd).
	https://theqwertiest.github.io/foo_spider_monkey_panel/

	Playlist Tools (along SMP) is not required but strongly recommended  to fully
	integrate SMP with the online controller, get Ouput Device, DSP, menu entries,
	dynamic button generation and allow Playlist Tools macros and tools to be used.
	https://regorxxx.github.io/foobar2000-SMP.github.io/
	
	Playlist Manager (along SMP) is not required but strongly recommended  to be 
	able to manage playlists -as files- without cluttering the UI with tabs.
	https://regorxxx.github.io/foobar2000-SMP.github.io/

	Run Command (foo_runcmd) is not required but strongly recommended to get
	some advanced features working (allows running statically created menus via cmd).
	It should be built-in on foobar2000 1.5+ installations.
	
	Run Main (foo_run_main) is not required but strongly recommended to get
	some advanced features working (allows running dynamically created menus via cmd).
	https://marc2k3.github.io/run-main/		(or included on github release)
	
	Youtube component (foo_youtube) is not required but recommended to get
	used along the new contextual menu buttons (the default buttons use it, but you can
	change it to anything you want). (*) As is, allows to look for tracks by same artist, 
	tracks where the artist is featured, instrumental or cover versions.
	https://fy.3dyd.com/home/
	
	Quickseatch UI element (foo_quicksearch) is not required but recommended to get
	used along the new contextual menu buttons (the default buttons use it, but you can
	change it to anything you want). (**) As is, allows to look for tracks by same title, 
	artist, genre or style. Note the 'search' patterns are totally configurable, so you
	can tweak them to do anything you want (like a "dynamic query" applied according to
	selection). Playlist Tools has a more advanced version of that feature -dynamic queries-.
	https://www.foobar2000.org/components/view/foo_quicksearch

	(*) At 'Preferences/Youtube Source/Search' playlist behavior, destination, tags, 
	number of tracks, etc. can be fully configured. Properly configured, can be used
	to merge tracks from library and results from youtube, replacing completely the need
	to use foobar independently. And all can be managed from the controller.

	(**) At Preferences/Media Library/Quicksearch', checking 'Set focus to search results'
	will allow the server to automatically show the new playlist on the controller. 
	Playlist name for those searches can be set too and even append the query to the name.

*** Installation

	Extract archive contents retaining directory structure into %YOUR_FOOBAR_PROFILE_PATH%
	For ex: mine is c:\Users\xxx\AppData\Roaming\foo_httpcontrol_data\ajquery-xxx\...
	For portable installations >= 1.6: .\foobar2000\profile\foo_httpcontrol_data\ajquery-xxx\... 
	For portable installations <= 1.5: .\foobar2000\foo_httpcontrol_data\ajquery-xxx\... 

*** Usage

	Open http://127.0.0.1:8888/ajquery-xxx/index.html in your browser.
	(Note that IP address and port is configuration specific and may
	be different in your case.)

	The interface should be intuitive enough as it is by itself, except:

	1. Double clicking playlist item starts playback.

	2. Single clicking playlist item selects item(s):
		2.1. Clicking on album name selects contiguous tracks from album.
		2.2. Clicking + shift on album name selects multiple albums.
		2.3. Clicking on track name selects the track.
		2.4. Clicking + shift on track name selects in between track(s).
		2.5. Clicking + control on track name adds track to selection.
		2.6. Right Clicking opens contextual menu for selection.

	3. Double clicking on status bar sets focus on playing item.

	4. Dragging playlist item or selection moves it within the current
	playlist page.

	5. Playlist slider is working as playlist page switcher, drag its
	thumb to change page.

	6. A few hotkeys are available (check command buttons tooltips for
	hotkey values).

	7. Use Shift+PageUp and Shift+PageDown to resize playlist.

	It is recommended to enable "Cursor follows playback" option in 
	foobar2000 Playback menu for more convenient playlists browsing.

	You are free to change template parameters by editing ajquery-xxx/config
	file. For example, playlist_items_per_page variable is useful when you
	want to permanently modify playlist page size.
	
	It's also recommended to uncheck 'Log access to console' at
	'Preferences/Tools/Http Control' on foobar (to not pollute console).
	
*** Updates over old ajquery controller

	This is a non-extensive list of main changes done to the controller:
		- Tile, artist, album tags are cut at display to soft-force one track per row.
		- General tweaks to UI placement, space usage and fonts (larger).
		- Rating is now shown on the playlist list for every item (stars).
		- Themes: dark/light. (new themes may be easily added editing the html)
		- Default 20 items per page.
		- Artwork: non-playing and non-artwork found images are now animations.
		- Extended controls reworked: rating and Custom contextual menu Buttons.
		- Playlist Tools: Spider Monkey Menus, Output Devide & DSP selection.
		- Integration with Spider Monkey Panel and Playlist Tools (SMP script).
		- Dynamic icons, menus, tooltips and component checking via SMP.
		- Toggleable log panel (usually used to display console log from foobar).

*** Theme

	Dark or light themes can be set at 'xxx\config-theme.json'. Dark is the default.
	Don't forget to also change default artwork images to at 'img\...' to their dark
	background counterparts! To do that set the http control config file ('config'):
		- albumart_not_found=ajquery-xxx/vinyl-playing-dark.gif
		- albumart_not_available=ajquery-xxx/vinyl-dark.gif
		
	Alternatively you can run '_switchTheme.bat' to process all required changes at once.
	
*** Dynamic color theme

	There is also an option to completely change the player colors based on album art,
	similar to [Georgia-ReBORN](https://github.com/TT-ReBORN/Georgia-ReBORN). It's enabled 
	by default. In case the artwork is hidden or playback stopped, theme fallbacks to the 
	light/dark setting.
	
	Option may be set at 'xxx\config-theme.json'.

*** Console log

	The panel displays the last 10 lines of log file present on this location: '.xxx\console.log'

	It may be used to display any relevant info from the server, either by a third party
	component (foo_np_simple, Spider Monkey Panel, etc.) or the foobar console itself.
	
	To save the console to a file use 'View/Console' and check 'Write Log' at bottom and use
	the previous path. Note this option gets unchecked on every foobar startup (so it's more 
	useful on 24/7 severs). It's also recommended to uncheck 'Log access to console' at
	'Preferences/Tools/Http Control' on foobar (to not pollute console).

*** Extended Controls (advanced features)

	This window has general tools for playlist/track management, among them you will find:
		- Run CMD: Run an arbitrary contextual menu on selection.
		- Rating: from 1-5, +, - and reset for the current selection.
		- Custom contextual menu Buttons: pre-defined tools associated to tracks context menu. 
		Can be set at 'xxx\config-contextmenus.json', from menu, to description, icon, ... (*) (**)
	
	(*)	When Playlist Tools (Spider Monkey Panel script) is installed, component checking is
	also allowed. i.e. 'smp\components.json' is automatically updated according to foobar
	config, therefore Contextual menu Buttons are enabled/disabled according to the components
	installed. Examples can be found at 'smp\defaults' folder
	
	(**) The default contextual buttons make use of foo_quicksearch along title, artist and genre
	queries. Style is not a query provided by default when you install the component but it can be
	added with this data: name: Style, query: %style%, context menu: checked (then press add)

*** Playlist Tools (advanced features)

	When Playlist Tools (Spider Monkey Panel script) is installed on foobar server,
	menu entries, output devices and DSP list will be available (*): 
		- Playlist Tools menu entries: disabled unless the associated menus is also
		enabled at 'Script integration\SMP Main menu'.
		- Output Device: disabled unless the associated menus is also
		enabled at 'Script integration\SMP Main menu' OR 'foo_runcmd' and 'foo_run_main'
		are both installed. When the latter happens, CMD method will be always preferred.
		- DSP List: disabled unless the associated menus is also
		enabled at 'Script integration\SMP Main menu' OR 'foo_runcmd' and 'foo_run_main'
		are both installed. When the latter happens, CMD method will be always preferred (*).

	When using Playlist Tools method, and 'Script integration\SMP Main menu' relevant config 
	is set, then you can change the Output Device or the current DSP on server by selecting 
	the desired entry on the drop-down list and calling the associated menu button. (****)
	Only one device/dsp can be set at the same time (the playlist used to send the command will 
	be cleared every time you set a different selection) List is also cleared after command execution.

	Playlist Tools menu entries work the same, but they allow multiple commands execution. 
	Everytime a menu entry is selected, the command is added to the server list. (****)
	Clicking on  the associated menu button executes the entire list and clears it.
	
	(*) The panel is the one sending those lists to the server. Whether you enable or not
	the rest of the features, so it's a 'requirement' to see the actual devices or DSPs on
	the controller on real time. There is a 'workaround' if you don't use SMP and/or Playlist Tools
	though: you can manually edit 'smp\dsp.json' and 'devices.json' according to your PC config.
	Examples can be found at 'smp\defaults' folder.
	
	(**) CMD method just uses simple command line to send the commands. Since it's cleaner
	(no playlist involved), it's preferred whenever it's possible. Obviously, it doesn't work
	for anything outside standard foobar main menus... so its usage is limited to those cases.

	SMP buttons always work, whether you have Playlist Tools installed or not. But without the
	panel they miss a lot of functionality:
		- Icons are dynamically set according to the menu type.
		- Show if menu is enabled (custom icon or check circle) or disabled (crossed circle) (***).
		- Tooltip showing menu name, function name and description if available.

	(***) Therefore, without Playlist Tools, the icons always show a crossed circle, since the server has
	no way to check if the menus are enabled or not. SMP Buttons data can be manually added/edited at
	'smp\smpmenus.json' as workaround for servers without Playlist Tools. 
	Examples can be found at 'smp\defaults' folder.
	
	(****) IT'S MANDATORY TO DISABLE 'ALWAYS SEND NEW FILES TO PLAYIST' 'AT PREFERENCES/SHELL INTEGRATION', 
	¡otherwise the commands will be sent to the wrong playlist!. See 'img\_doc\always_send_new_files.jpg' image.
