Implemented Preetham Sky Shader.
Adapted from: https://www.shadertoy.com/view/llSSDR
Currently only supports DX9 due to the complexity of the number of shader instructions.
In Hammer you can assign the shader to the skybox under map>map properties > skybox texture name> realistic_sky.
There is no implementation for automatically sampling the light_environment, but this should probably be done by the gamemode, to allow for custom controls through the exposed shader parameters.
