URL rewriting: works with image file instead of image id (change
make_picture_url to generate urls with file name instead of image id)
URL rewriting: completely works with category/best_rated and
picture/best_rated/534 (change 'category.php?' to 'category' in make_index_url
and 'picture.php?' to 'picture' in make_picture_url to see it)
fix: picture category display in upper bar
fix: function rate_picture variables and use of the new user type
fix: caddie icon appears now on category page
fix: admin element_set sql query was using storage_category_id column
(column has moved to #image_categories)
fix: replaced some old $_GET[xxx] with $page[xxx]
fix: pictures have metadata url (use ? parameter - might change later)
