Enable editing a dive that was manually entered.

This patch enables editing a dive that was manually entered,
it doesn't cover dive plans yet because on the plan I need to
figure out what are the 'user-entered' points, and what are
the algorithm point. and I feel lazy. =p

One last thing that's missing is to revert the dive to the
previous condition if the user cancels the edition, currently
canceling and applying ok is the same thing.
