New Painting Tool. Colour Constructor!

[DK]

Love it so far. Lets you play around with some color schemes and gives you the list of colors in the scene. Very useful little tool.

I think once you have that list implemented it will be very nice.

Here are some things off the top of my head that could possibly be added in:
- Different materials on the objects?
- Different shapes e.g. Cube, Triangle, Sphere
- "Glassy" Transparency slider on objects?
- A few preset color schemes
