adapter (start a scan, etc).
BluetoothDevice: Represents a remote BT device. Operations on remote devices
(pair, connect, etc).
This widget allows uses to turn on/off bluetooth, wifi, gps, and sync,
and adjust brightness without going through the settings menu.
The widget provider updates the settings when the buttons are pressed.
The widget provider is also a receiver for events indicating that the
status was updated elsewhere and the buttons need to be changed.
