RGB Shades Hue Section Mod

I added some RGB Section code to the RGBShades.
It lets you visually (or automatically) select a start hue color, as well as a stop color, and the rest of the glasses effect will scroll through these colors instead of the entire rainbow.

This is my first time touching arduino, so nothing too magical yet, but I wanted to share it regardless.
