Inform LocationFilterModel of changed dive site name

Browse source 
Since commit 01d961086c, the location filter
list is updated if a dive site is edited. The problem is that if the
name of a selected dive site is changed, the selection is lost.

Therefore, before repopulating, inform the location filter that a dive
site changed its name. The location filter then internally changes the
name and can properly transfer the old selection on repopulate. This is
performed via the new LocationInformationWidget::nameChanged signal,
which is connected to the new LocationFilterModel::changeName slot.

A special case to be handled is the following:
 [ ] Site 1
 [x] Site 2
and "Site 2" being renamed to "Site 1", i.e. both sites being merged.
Here, the merging is detected and "Site 1" will likewise be checked:
 [x] Site 1
 [x] Site 1
No merging is performed, as the list will be repopulated anyway.
