Only calculate deco stops in planner mode

In add dive mode simply bring the diver safely back to the surface
(currently with a fixed ascent rate of 30ft/min (or 9m/min)).

We should make that rate configurable (for the planner as well as the dive
add function). Also, the dive add function should offer to automatically
include a safety stop.
