Implement BT settings functionality for new UI.

- Removed context menu logic for long press (no longer used).
- Converted device picker to run in its own Activity, using a dialog
  theme on large screen devices and full-screen on phones.
- Removed unused resources.
- Add device to "Paired devices" list when pairing is initiated by the
  remote device.
- Return to Bluetooth settings pane after successfully pairing a new
  device from the "Find nearby device" pane.
- Add support for renaming devices (TODO: persist the custom name and
  update the "bread crumb" in the action bar to the new device name).
- Add support for incoming file transfer and auto connect checkboxes
  in DeviceProfilesSettings.
- Show available and connected device profiles as icons instead of
  summary text. Available but disconnected profiles are drawn in gray.
- Fixed bluetooth_notif_message to include the device name as a parameter
  instead of appending the name to the end of the localized string.
- Changed some fields from private to package scope for more efficient
  access from inner classes.
