Fixed some really stupid bugs.
Added Stage PrimitiveProcessing + functions to configure culling (#28)
Added DepthTest options (not tested, but they should work) and added missing file for PrimitiveProcessing (#28)
Cleaned up Program and HotProgram
Renamed TexCont to HotTexCont...
Start to implement TexCont to prime multiple texture at once...
New Texture structure...
TexCont can now prime all it's textures with one prime call. This is a proper replacement for #31
