- added a few more texture coloring options to the shader.

Browse source 
Aside from adding an additive component it can now also do:

- desaturation (not limited to the range of 0..1 so it can also be used for oversaturation by applying a negative number or negative saturation by going above 1.0.
- invert the texture
- apply a blend, including 3 special mode taken from EDuke32.

Currently only the implementation is done, it is not exposed to UDMF yet.
