Subject: [PATCH] Add button to rescan BT devices

Otherwise the divecomputer has to be in pairing mode
at app start time.

Unfortunately, this leaves less space for the progress message.
My time/qml knowledge does not suffice to move that to the next line
(when moving that out of the RowLayout it overlaps with
the buttons).
