Basically in preperation of supporting colourblindness modes I implemented the following link when loading palettes.
http://http.developer.nvidia.com/GPUGems2/gpugems2_chapter24.html

This basically means I can do whatever the hell I want to the colour profile of incoming paletties, and nobody can stop me. Muahahahaha etc.

Also, I added a saturation feature to show off its full potential, converted gamma from a table to a factor of the calculation, tweaked some menus and made the default value of cvars show up on sliders. Because that's how I roll.
