Commit XRT

This commit contains project XRT. XRT is an advanced game engine built
to run effieciently on an inefficient platform. Current code metrics
show it's capable of running demanding loads at 30fps on as little as a
2.0GHz Intel/AMD along side a GPU released after 2006 (OGL 2.1) - think
Radeon HD2400 / GeForce 8400GS / Intel GMA 3000. 

I anticipate that none of you will have any issues. If you do, the
University PC's are packing Quadro's so they certainly won't.

XRT supports:
Sequential Update-Render loop
State Manager (SceneGraph)
MP3/Wav/Ogg/Aiff audio
Keyboard input (adding in mouse and controller)
Graphics2D rendering via Renderer
Scripting with LUA

More to come...
