Once again try to fix the selection

Browse source 
Things got broken. Again. We no longer kept track of the selected dives in
our structures which broke statistics.

This attempts to fix that, but appears to still have a bug when selecting
trips. Sometimes this results in 0 dives being selected according to our
data structures, while Qt happily shows all dives of the trip as seected.
