Move the code to add the first selected dive site from MapWidgetHelper::enterEditMode() to MapLocationModel::reload(). Thus, the list of sites is built only at one place. For this it is necessary to pass a pointer to the map, so that new dive sites can be added at the center of the map. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
