Subject: category random replaced by a more generic category : list. You give
 a list of element identifiers and it creates a page virtual temporary
 category. random.php generates a randomized list of element id visible to the
 user (according to permissions) and redirects to category.php.

Major problem : elements order is in id ascending order, I don't know how to
change order when having id1,id2,id3 and id2,id3,id1 (the display order is
the same)
