The Mega Change Of Doom - or, fixing Stop. Almost. At least it's better than before. However, the OpenGL plugin seems to lose textures a lot between game restarts :P I think the GL plugin needs to do a lot more cleanup.

This change also includes tons of minor code formatting cleanup. Yeah, should've separated it ... sorry :(

Kills the old CPUCompare support. I'll resurrect it if I need it again, right now it mostly clutters the code.
