feature 251: Rating For Anonymous users

fix: page['items'] for favorites category and remove old use of $has_next, 
$has_prev in picture.php (slideshow and favorites section)

optimization: one less sql query in picture.php when there are no comments

display of the refresh url in redirect.tpl (useful when debugging with 
browser meta redirects disabled)
