Many improvements

PermGen can be tweaked from the settings menu
Groups are saved on change/exit
Install target is no longer completely broken
All the deplibs are now static
Added notes dialog
Fixed ini file format support (can save strings with newlines, tabs. UTF-8 is explicitly used!)
Rename button now uses line breaks so it doesn't grow ever wider (Added a custom tool button subclass)
There is now a CAT button. Meow.
