Increased amount of hues and variations in saturation and brightness. Fully grayscale colors are now possible too.

Expanded the color picker to replace ALL color pickers, not only the hair color one anymore.

- Made compatible with improved hair menu

- Zombies won't spawn with the new hair colors anymore
- Colors are now picked in two steps, first picking a hue, and then a saturation and brightness variant in a different color picker window.
