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.
