Killing Zone code merged back to Ainur

I merged back the Killing Zone code to Ainur which become a DLL.
The Ainur library is now statically linked to OIS with XInput support, Caelum, TinyXML and PagedGeometry.

The Killing Zone SVN now contains only the small executable (it's only a simple main.cpp), solution/project to link to Ainur.dll and game data.

Anyway given the incredible modularity, you can actually make games with a small main.cpp file and let Ainur do the rest or create your game states subclassing Ainur's classes to fit your needs.
