Add the ability to edit the date/time of a dive

This can cause some fun unintended side effects - especially when the dive
is part of a trip and the new date/time moves this into a different trip.
Instead, trips get split and the overall result is consistent, but a bit
unexpected.

But since this is designed to help people right after a dive import in
case the clock on the dive computer was wrong, my guess is this won't ever
be a problem for actual users.

Fixes ticket 18
