Pi GPIO support

Let Raspberry Pi users read/write to GPIO. Not sure about the best approach (extension?).

TurtleBots, an unmaintained fork of TurtleArt, has numerous GPIO capable plugins for various hardware and robots available at the time. It's not in our GitHub organisation yet, but is available for download inside Sugar.

Turtle Bots is essentially a set of plugins to Turtle Blocks. You should check to see if there is a plugin that already does what you need.
