Lubomir I. Ivanov 7486682f43 mapwidget: add the "skipReload" guard
This guard is to prevent a meaningless reload on the map marker list,
when the user selects a new dive and nearby dives. The flag is updated
in selectedDivesChanged() which on it's now cannot possibly trigger
changes in the markers, only the selection. The selection of active flags
is already handled by the model and automatically updated in the QML.
