DragAndDropHelper::updateDropAction: use StatJob for remote URLs

When dragging onto tabs/Places from a remote URL, we don't process
the QDropEvent immediately, but start a StatJob and process the
event when it finishes.

Also, the result of the StatJob is cached for 30 seconds, to avoid
starting duplicate jobs.
