GRIMRenderer broken

[reinago]

Indeed the GRIMRenderer can still be faster than NGSphere if bricking is done properly, I observed 2x FPS for laser.big, but in the current state it's broken since the referenced shader snippets were renamed and possibly changed around a little bit when all the sphere shaders were combined into one.

For reference, the ISC_Demo_IceT tag has a fully working GRIM renderer, just capture the shaders from there and check what's broken.

This helps getting rid of the warnings, but I think I still mislinked some snippet:

Will be fixed in pull request #278.
