The DiveListView had a singleSelectedTrip function that returns the selected trip if exactly one trip is selected. This could be very slow if numerous non-trip items were selected, because all the selection indices were back- translated by the proxy model. This could make selection changes very slow, because the MainTab used said function to determine whether it should show trip or dive data.. Indeed, with a 3500 dive test log, when selecting all dives in tree mode, the updating of the TabWidgets is sped up from 130 ms to 5 ms this commit.
