- 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) git-svn-id: http://piwigo.org/svn/trunk@657 68402e56-0260-453c-a942-63ccdbb3a9ee
