Moved FiveUpgrade.inc to upgrade1_5.php and made FiveUpgrade extends Maintenance since nothing else is using this class

Todo: maybe just remove this script entirely since it's useless for most people and parts of it are just broken, e.g. calls to wfImageDir() and wfImageArchiveDir() that were removed in r22580.
Modified paths:
  • /trunk/phase3/maintenance/FiveUpgrade.inc (deleted) (history)
  • /trunk/phase3/maintenance/upgrade1_5.php (replaced) (history)
