Fixed the Bluetooth On/Off Checkbox in settings so it is enabled/disable properly.

In the BroadcastReceiver, pickup the new bluetooth status from the intent instead
of calling back to LocalBluetoothManager.  There could be race condition since
LocalBluetoothManager itself gets the same info via the BroadcastReceiver mechanism.
Also cleaned up logs.
