Add option to increase font size

[ghost]

Is there a way to increase the font size in Linux?
I can't find something something like this: java --font-size=18 -jar kouchat-1.3.0.jar

[blurpy]

If you use the Metal look and feel you can try this as a quick fix:
java -Dswing.plaf.metal.controlFont=Dialog-18 -Dswing.plaf.metal.userFont=Dialog-18 -jar kouchat-1.3.0.jar

I will look into adding a better option in the Settings later.
