Hook up adding a dive

This gets things mostly right.

It creates a dive and uses the planner widget to create samples which are
copied into the dive. It fills in some reasonable defaults (DC model,
timestamp), but doesn't allow editing the timestamp (or the temperatures
and air pressure).

On accept the planner gets reset and the dive appears correctly in the
dive list.

Cancel still needs to be handled.

And I bet there are many subtle bugs lurking here and there. But it's a
start.
