Berthold Stoeger 0da86dfd86 Map: in edit mode place no-gps dive sites at center of map
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.
