Undo: unify selection behavior in dive-list commands

Browse source 
Some commands tried to retain the current selection on undo/redo,
others set the selection to the modified dives.

The latter was introduced because it was easier in some cases, but
it is probably more user-friendly because the user gets feedback
on the change.

Therefore, unify to always select the affected dives on undo()/redo().
