- user permissions ask update at each admin page generation. Table

user_forbidden must be updated only if current user is not in
  administrative section

- bug fixed : category.php, error on page title when non category selected

- admin/search : bug on variable $PHP_SELF, replaced by $_SERVER['PHP_SELF']

- admin/user_perm : inheritence management. When a category become
  authorized, all parent categories become authorized, when a category
  become forbidden, all child category become forbidden

- no more recursivity in delete_categories function

- new function get_fs_directories for future new method of synchronization

- new function get_uppercat_ids replacing several pieces of code doing the
  same

- new function get_fulldirs used for metadata function get_filelist and
  future new method of synchronization

- new function get_fs for future new method of synchronization

- typo correction on lang item "about_message"

- no link to category privacy status management on user permission anymore
  (giving the menu item instead)
