Add ability to replan a dive that we planned before

When doing this, all waypoints of the calculated ascent are now waypoints
in the plan - so the user has to remove the ascent part of the dive in
order to really replan the dive. That's a pain, but we don't keep the data
around that would tell us which waypoints are user input and which ones
were calculated.

Fixes #527
