Dive site: inform model of dive site addition / deletion

Browse source 
Introduce two DiveListNotifier signals which are sent by
the undo commands if dives are added to / removed from the
core.

The signal has the dive site and the index in the global
dive site table as payload. Thus, the model has only to
remove the appropriate rows.
