Berthold Stoeger 488eb15423 Desktop: show all selected dive sites on click
When clicking a dive site on the map, the QML code would set
the selected dive site, but then all dives of dive sites in
the vicinity were set. But still only the clicked-on dive site
was shown.

Therefore, don't set the list of selected dive sites in QML,
but later in DiveListView::selectDives(), where we know all
the dives that were selected.

This, again, gives nasty entanglement of diverse widgets and
models.
