Filter: update counts if dives added / removed

Browse source 
Update the filter counts if dives were added removed by the
undo commands. The undo commands call into the filter model
at the right time so that hidden_by_filter is already set.
The filter model keeps track of the counts and emits a signal,
which is caught by the widget.
