[feladat @ 83] Bugfix: the list_zones.php wasn't listing zones correctly if a zone didn't have an owner. Bugfix: the list_supermasters.php never listed more then one supermaster, even if there were more. Both bugs were reported by Jasper van Erven Dorens.

[feladat @ 82] Fixed a bug in add_zone_master.php.

[feladat @ 81] Bugfix. If the number of zones exceeded the "max row limit" and a "starting letter" with no zones was requested in list_zones.php it would show no zones while incorrectly stating "showing 1 out of N zones".
