Get the selected dive site from the list

Hooked up an eventFilter on the QListView that displays our dive sites so
it would filter the keys enter and space, storing the current dive_site
uuid when that happens.

Also it stores the uuid on clicks.

Now we need to get that information when processing acceptedChanges() and
check if the uuid stored there == displayed_dive_site.uuid and also if
text != displayed_dive_site.name, because if the user didn't click on
anything but only wrote stuff on the LineEdit no dive site would be
selected and so uuid == displayed_dive_site.uuid (wich would mean 'no
changes')
