mapwidgethelper: add the selectVisibleLocations() method

Browse Source 
The new method selectVisibleLocations() contains a routine
to find all visible MapLocation objects in the Map viewport and
select the dives associated to said MapLocation objects.

This method is to be invoked from the QML context menu.
