The gas and dive-type models were repopulated in the
diveplanner model. The former are used in the planner.
However, the latter is also used outside of the planner,
when editing non-planned dives. Thus the former shouldn't
be repopulated by the latter, but by the code that needs
it.
Side note: repopulating the dive-type model seems to
make no sense whatsoever since the values never change,
but let's keep it for now.
