Dive list: propagate current-item to frontend

The command-objects select a current item, but this selection
was not propagated to the front-end. The current item is the
base for keyboard-navigation through the dive-list and therefore
should be set correctly.

It took some experimentation to get the flags right:
 QItemSelectionModel::Current
Hopefully, these are the correct flags across all supported
Qt versions!
