Dive list: add context menu function to renumber dive(s)

No attempt is made to ensure that what the user does is sane. So this can
result in duplicate numbers, non-consecutive numbers, non-monotonous
numbers, whatever floats the users boat.

You can renumber a single dive or all selected dives (with a starting
number given that is applied to the oldest selected dive and then for each
newer selected dive that number is incremented by one).
