- change "->" in a beautiful arrow :-) for categories level in admin

- single category management screen updated : commentable and uploadable
  properties added, full directory displayed, status and visibility
  properties update uses inheritance, user favorite elements check moved to
  somewhere else : would be too long to calculate here for too many users

- new admin functions set_cat_visible and set_cat_status : visibility and
  status updates can be done in cat_options and cat_modify

- language : differentiate "locked" (state) and "lock" (action)
