Sumobot Chassis v2

This is the next iteration of my original sumobot design.

A few changes:
* It\'s made from three pieces, not one
*It uses two solarbotics GM8 gear motors (actually the pololu 120:1 equivalent), instead of continuous servos
* It works.

I\'m really happy with how it came out.

**UPDATE**
I\'ve updated the files since I first posted this thing. They\'re pretty small tweaks but they really help when trying to wire up the whole thing and hold down the electronics.
