Subject: [PATCH] mapwidget: connect the helper selectedDivesChanged() signal

The selectedDivesChanged() signal from MapWidgetHelper is connected
to a local slot. One problem here is that this crashes with the calls to
DiveListView().

The dive list widget triggers events that call reload() on the MapWidget
(same happens for Marble's Globe class) and that crashes somewhere in
the QML shared library. TODO: investigate.
