More trip manipulations: remove selected dives from trip

Browse source 
There are a few obvious trip manipulations on multiple dives that haven't
been implemented, yet. This commit handles the case when we have multiple
dives selected and right click on one of them. It now removes all of those
dives from their trips (instead of just the one that we clicked on).

Still todo is the inverse operation. Select a group of consecutive dives
and turn them into a trip.
