Introduce recreational planner mode

This adopts the planner to the needs of the recreational diver. Rather than immediately
starting to ascent doing deco stops this mode, this mode stays at the last manually
entered depth for the maximal time before mandantory stops appear (NDL). It does not
change gas but keeps using the last used cylinder.

TODO: * Grey out unused UI elements of the planner in this mode
      * Start ascent before gas runs out (or into reserve)
      * Do a 3min @ 5m safety stop.

Fixes #840
