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 $confallow_random_representative = true;
