mobile/filter: derive numShown from a new Q_PROPERTY

Browse source 
The number of dives was updated when the model of the list was
changed. Since we removed the multi-threading, the model is
not disconnected/connected anymore and therefore we don't get
the appropriate signal. Instead of introducing a different
signal, make the shown-value a Q_PROPERTY. Thus, we can easily
send a changed signal if we have to.
