OrderedFolderSupportPatch

  This is a patch-product that modifies ObjectManager to allow folders to
  be ordered by the user. However it does not comprise any user
  interface.

  ObjectManager gets new methods:

    - get_object_position(id)

    - move_object_to_position(id, pos)

    - move_object_up(id)

    - move_object_down(id)

    - move_object_to_top(id)

    - move_object_to_bottom(id)

  This product is derived from OrderFolder by Stephan Richter, iuveno AG.
