Florian Müllner fcd08fae94 status/bluetooth: Split out BtClient object
The new class abstracts away the nitty-gritty of bluetooth- and
airplane-mode handling, and exposes just what the UI needs.

This will become more important with quick settings, where there's
a stronger separation between top bar icon and quick toggle.
