maplocationmodel: add a "selectedUuid" property to MapLocationModel

Inside the QML Map class there is a MapItemView item.
This item uses a delegate that receive a "model" property from
the MapLocationModel, but infact that's a QObject with the MapLocation
defined properties. That's how MapItemView works.

The problem here is that "model" QObject cannot be cast back
to a MapLocation as the meta data in there does not include
a MapLocation sub-class, for some reason.

Even if using propery() on that QObject to fetch data like coordinates
works, instead of storing this strange object pointer, store the
MapLocation UUID (from dive_site) which is a uint32_t.

setSelectedUuid() deals with this oddity and finds the correct
MapLocation pointer in the table and dispatches a selectedLocationChanged()
signal for it.
