First attempt at fog ;)

For the moment, it works just on Basic / Lambert / Phong materials.

Fog must be added to the scene before initialization of WebGLRenderer and scene must be passed to WebGLRenderer constructor (like for lights).

I don't know yet how to solve properly MeshShaderMaterial & co :(
