Enable editing the 'Add dive' from the new profile.

This is highly broken in many ways - but it's the right first step.
I ported two of the most important methods from the old profile and now if
you are in add dive mode, double clicking on the new profile will
correctly add a handler on the planned dive. To see and move the handler
around, however, you need to activate the old planner.

Next step: add the handlers on the new profile.
