Select child folder when navigating to a parent folder

Whenever the dolphin view is initialized to show the contents of a new URL
(e.g. "/home/x/test") it will be checked if the new URL is a parent of the
previous displayed URL (e.g. "/home/x/test/documents/aaa"). If the check is
successful, then the common child (in this example: "/home/x/test/documents/")
folder item will be selected and scrolled into view.
