RPi and camera support for Printrbot Simple Maker's Kit (1405) version 2

The [Printrbot Simple Maker's Kit](http://printrbot.com/shop/simple-makers-kit/) is a wonderful small 3D printer with loads of potential. [Octoprint](http://octoprint.org/) has a special distribution for the [Raspberry Pi](http://www.raspberrypi.org/) called [OctoPi](https://github.com/guysoft/OctoPi) which allows one to load STL parts, print and make time lapse videos via local network and free your computer from the burden of being attached to the printer for while it's printring.
