Do min/max pressure and temperature based on the non-surface data

Browse source 
Do the min/max calculations only *after* we have removed the extra
surface events at the end.

The Uemis data in particular has a lot of surface events after the dive,
and we don't really want to take them into account since we won't be
plotting them anyway.
