Implement get_divemode() to find the divemode at a particular time

Browse source 
Replaced a rather cumbersome function that that did the above. Upon
the suggestion of Robert Helling who proposed a much shorter way,
this new function replaced the previous ones. This necessitated
changes to divelist.c, profile.c and plannernotes.c, as well as
dive.c/h.
