desktop: move planner-code to diveplanner.cpp

Around 2015 there was a push to move planner UI code from
mainwindow.cpp to diveplanner.cpp. That never was completed,
presumably because the planner is actually three widgets.

Collect these widgets in one PlannerWidgets class and move
the code there.

This is not a full dis-entanglement, as the plannerwidgets
have to access the profile via the mainwindow. But at least
it collects the planner UI code at a single place.
