Request: Ability to load custom cursor

While playing RotMG in full screen, I lose the cursor in a sea of bodies and end up shooting in random directions. It would be nice if I could define a custom cursor bitmap in ISBoxer, and force that to be used instead. It would be even cooler if I could load a different cursor depending on which window was active since the cursor is duplicated in all windows.

Sounds reasonable, I'll add this to my list of things to do
