A device now has a busy flag (set during synchronization). While busy,
no other communication with the device shall occur (TODO)
Refactors the non-bluetooth actions a bit #45
Next step: make use of the busy state in ControlCenter (show
a busy cursor) and in BluetoothCommunicationService (to not call other
operations while busy)
Otherwise the result handler might be called before the wait-latch
has been created, leading to a deadlock of the thread.
Also: only wait for read- and write actions, but not for wait-actions.
1) The MAC address has to be added manually for now (Settings -> Debug)
2) Configure other notifications as desired
3) After doing that, restart Gadgetbridge, after that, the device should
be visible.
4) Tap it to connect
5) Try the Debug activity via the Menu to send some dummy notifications
=> Your MI should vibrate and blink
Also: add some extra files necessary to support Eclipse ADT. To be
migrated to Andmore, later.
