Undo: keep frontend informed of changes to dive site count

Add a new signal to DiveListNotifier. Send signal if dives are
added or removed and therefore the dive count of a dive site
changes. The dive sites are collected and the signal is sent
at the end of the command.

Add code to update the table view.
