mobile: enable switching BT on/off during session.

Browse source 
This commit implements possible switching BT on and off during a session,
so not needing a restart of the app when the user forgot to switch
it on when starting the app.

For this, the following needed to be done: 1) create a handler that
reacts on local BT device status changes. 2) repopulate the connection
list in the download screen when a BT status change is detected.

Notice the subtile change of the Q_INVOKABLE btEnabled() function
to a Q_PROPERTY. This gives a nice dynamic behaviour when
switching BT on/off with the app open.

Fixes: #556
