New device support and RGB saturation bug fix

[scooterpsu]

This adds support for the BlissLights Sky Lite Evolve Star Projector

Essentially an RGB light with a switch for the rotation motor. The rotation could be broken out into a brightness slider, but at max speed the movement is too subtle for me to justify the effort. Other models come with laser stars, which would require additional switches.

Pulling from the existing RGBOutlet code I also found an bug with saturation in the existing RGB implementations.
