Let search results be dragged onto a folio like the tree

Browse Source 
While a collection search is active the tree is replaced by the flat
ranked list, and that list had no drag support: dragging a result only
moved the selection. Anyone used to searching and then dragging lost the
drag as soon as they typed.

The tree's drag is moved into a static ElementsTreeView::execElementDrag()
taking the source widget, and the results list uses it from the path each
row already carries, so the drag content and pixmap are the same.
