Upgrade to ColorControl for interactive creation of effects

Significantly upgraded ColorControl, the interactive GUI for making it easier to create you own dynamic color effects.
It is now possible to handle several devices, to save and load the created effects, and to dynamically see what happens to the effect when colors are changed.

Added ColorControl for interactive pattern creation

Added ColorControl, an interactive GUI for making it easier to create you own dynamic color
effects, based on the 3D color picker and a selection of previously defined effect types.
When started it launches a window in which you can first create a color scheme,
then select the wanted effect type, and finally upload it to the leds.
