Subject: Show the parent folders in the breadcrumb menu when on a child entry.

Previously, clicking on an menu item in the breadcrumb menu removed the
parent entries of the path, i.e.:
Clicking on the "to" entry in "/path/to/some/folder" changed the
breadcrumb menu to show only the "/path/to" entries.
With this change the breadcrumb menu changes this behaviour as the full
path is still visible (and usable) but with the "to" entry beeing
highlighted.
