Moved bluetooth scanning to BeaconManager, test case

-Added 4 beacons that I was testing with (4 iPhones)
-All scanning code has been moved to BeaconManager
-Separated out the path_loss_d0 and path loss exponent variables (so you
can modify each beacon's transmit power)
Gimbal is ours

-Discovered the mechanisms Gimbal uses to resolve its beacons, and
integrated this into our app.
-Moved things around in BeaconManager
Merging IOIOSimpleApp with our SmartRover app
Tons more additions and tweaks with beacons

-BeaconManager saves Gimbal resolves to an XML file so it doesn’t have
to contact the internet every time to resolve a Gimbal ID
-Tweaked GimbalManager for better concurrency
-Displayed beacon stuff on the UI (will probably have to be deleted)
Missing jar fils
