The trip selection code was an awkward layering violation.
Whereas dive selections due to dive undo-commands trickled
down via DiveTripModel-->MultiFilterSortModel-->DiveListView,
for trip editing, the DiveListView directly intercepted the
TripEdited signal.
Instead, mimic the dive-selection code. This is a bit longer
but more consistent and logical. The undo/redo of trip changes
is now also a "programmatical" change of the selection.
