Major include refactor; changes to pretty much everything This untangles some of the gigantic kitchen sink headers in an attempt to split things into smaller files. Also don't include gl.h, glext.h, windows.h, and other such nonsense *everywhere*. Lots of cleanups on the way too. More dead/unused code removal. Remove incrFlag(), decrFlag() Lua functions.
