Batch Colorization and foldering

Batch Colorization and folderingalinging things.

I have found no way to colourize more than one item. If we could have the ability to colourize groups of tracks this would save a lot of peaking and poking time.

I agree with others that folders should be merged with groups, so that a group can dominate routing. When we colorize a folder we shoud also be able to colorize all the contents of this folder - this is great for visuals in mixers
