Subject: utils/colors: move colors into subdir, add hsv

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).
