bug fixed: create_navigation_bar take into account clean URL if requested.
deletion: argument link_class (HTML class of links) in function create_navigation_bar was removed, useless since branch 1.5. bug fixed: rate_items are now a configuration parameter (set in config file) modification: new functions library functions_rate.inc.php to reduce picture.php length. bug fixed: categories were never expanded in the menu since clean URLs. bug fixed: changing pictures sorting order in main page was always rederecting to root category. git-svn-id: http://piwigo.org/svn/trunk@1084 68402e56-0260-453c-a942-63ccdbb3a9ee
