Add Coloured/Image Markers

[zysim]

Would be nice to have a way to differentiate different categories of items on the map. Maybe we could have a colour-coded system, like having green markers for feedbags, yellow markers for treasures, etc. (Maybe would also be useful to list the value of treasures too?) Otherwise, the markers themselves could have the image of the item, which of course we would need the images in the first place.

Planning to create custom icons for different types of things. Treasures will probably be grouped into 3-5 categories by value, and items with uses may each have an icon. Leaflet offers the ability to toggle things on the map in "layers", so we could even have treasures, animals, demon scrolls, trigger volumes, etc. on the same map.
