* Removed phong lighting from the point lights. Realized that I don't need a diffuse light algorithm for the point lights, they're fine with just attenuation and a specular algorithm.

* Cleaned up MCGBufferTerrainShader.psh a little, broke some parts into separate functions etc. Should perform slightly better now, too.

* As usual, some work done in geometry shader grass / geometry shader water. Just doing some tweaking to get better looks.
