Beaglebone sensor

My Beaglebone code is in a directory here; you don't have to merge if you don't want. The has_connections.py might be helpful though, for some code organization purposes. I also tried to use session authentication to avoid some password typing. This is forbidden for security reasons (cross-site request forgery stuff), and currently the server cannot handle my workaround, but my work so far is on my branch session-cookies if you're interested.
