getMapLocationForUuid() accepts a UUID, searches the MapLocation table
and returns a pointer.
Make use of the new method in setSelectedUuid().

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.

The "uuid" property will be the one from the dive_site. At first it
will also be used to track the active marker/flag selection.

This method should be used if many markers are added at once.
It's main purpose is to reduces the number of beingInsertRows()
calls.
Make MapWidgetHelper::reloadMapLocations() use it.

Instead of maintaining a seperate latitude/longitude values
in C++ and passing them to QML separatelly, pass them as a QGeoCoordinate.
This reduces the number of model "roles" and also prevents the creations
of extra objects in QML (e.g. via QtPositioning.coordinate(..)).

- add() will be used to add a MapLocation to the model with
beginInsertRows()...endInsertRows()
- clear() will be used to clear the model with beginRemoveRows()...
endRemoveRows()
NOTE: emiting dataChanged() does not seem to update the QML view for
this model so calling being<..>Rows() seems to be the "correct Qt
approach" to do this.

The QML Map widget requires a QAbstractListModel based model to operate
with good performance. Technically gpslistmodel.cpp can be used for that
same purpose (e.g. has GPS coordinates), but the way it updates
may complicate the Map widget integration.
Thus, a new model is created - MapLocationModel, with items of type
MapLocation, for an attempt for a clean project structure on the C++ side.
For now it only handles latitude and longitude.
