Raspberry Pi support for Finch

Raspberry Pi is a $35 palm-sized embedded computer. It can run Linux. The Finch now supports Raspberry Pi's official debian-based operating system. This means you can write, compile, and run Java, C, or Python code on the Raspberry Pi. The Raspberry Pi is small enough to strap to the back of the Finch, and we expect to be releasing a mechanical mounting solution for it soon, but for now you can still try out the software.
