2014-04-08utils/colors: move colors into subdir, add hsvAlexander Sulfrian6-0/+559
All color classes are now in an own subdirectory with a short name. The new class HsvColor represents the Hue/Saturation/Value color model and comes with conversion functions to and from rgb colors (currently integer arithmetic without optimization for higher presicion).
