Principia Paint! v1.3

v1.1, Added clear all button and fixed a problem with the sprite counter/undo
v1.2, fixed the issue of the sprites drawing when the draw type was selected, minor graphics fixes
v1.3, code cleanup, dragable color sliders...

Most of the intended features are up and running now, still need to expand some things and add a few more details, like paintbrush.

Enjoy! No Derivitives for now...sorry
