BlinkyCube - RGB addressable lights in the gear cube.

My wife was playing with Emmett's cube gears and suggested that it'd be cool with a light in it. If I'm going to all that trouble, I'm going to put in more than one light :)

I grabbed a few WS2811 pixels out of the project box and made a few changes to the cube, including scaling it up to 5 inches.

This is an early beta version of this cube. Instructions, wiring diagrams, etc will follow, and I'll probably make more changes to the pins.
