Small changes to the selection logic

Browse source 
Now it correctly uses the existing helper functions and keeps our idea of
the selection consistent.

There is a small behavioral change compared to the Gtk code. Range
selections no longer have the last dive clicked on as selected_dive but
instead the dive with the highest index that was selected. I don't think
that is a major issue for anyone.
