bug 937 fixed: makes sure a user won't see the thumbnail of a photo that has a
higher privacy level than user privacy level. For an acceptable solution at performance level, I have implemented a cache: for a given user, each album has a representative_picture_id. This cache also avoids to perform numerous "order by rand()" SQL queries which is the case when $conf['allow_random_representative'] = true; git-svn-id: http://piwigo.org/svn/trunk@8802 68402e56-0260-453c-a942-63ccdbb3a9ee
