q2w bsp format support.

automatic lightmap texture scaling to retain more performance on large maps.
r_clutter preliminary implementation should probably fix up the shader still.
CSQC_Parse_Damage implemented.
finally implement q2 inventory.
fix mixer overflow crash.
glsl can now use s_diffuse etc to force inclusion of a diffuse sampler/texture, meaning shaders don't need to include them.
fix issue with writeip
