Implemented palette ordering (issue 112). You can activate it in the secondary palette window (shift-P), it's saved in gfx2.ini.

The skin file has 2 more icons for the arrows (Ilija, grafx2 won't load if you don't update yours)
Updated contextual help for the secondary palette window.
Fixed some typos in code.
