maplocationmodel: implement the clear() and add() methods

Browse source 
- 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.
