Core: add add_dive_to_table() function

Browse source 
Up to now, dives were added to the global dive table with
add_single_dive(). Split out the funtionality to add a dive to
an arbitrary dive in the add_dive_to_table_function(). The
difference compared to record_dive_to_table is that dives
are added at a specific position or the sort-criterion given
by dive_less_than(). This will allow to use a dive tabe for trips
instead of a linked list.
