        * gtkfilesystemmodel.c:
        - Disconnect signal connections when appropriate.
        - Listen to ::roots-changed on the file system
        - When the last reference count on a child is
          removed, queue an idle to unload the parent.

        * gtkfilesystemgnomevfs.c
        - When URI's outside of file:/// are acessed,
          add toplevel URI's to the list of roots.
        - Improve display name computations

        * gtkfilechooserentry.c: Don't complete on empty
        file parts; free stored folder when base directory
        changes.

        * gtkfilechooser.c: Fill in some docs.
