itgwiki_mirror 0.0.25.pre

Use two scripts, itgwiki_mirror_backup and itgwiki_mirror_deploy, to maintain a read-only mirror of ITGwiki. itgwiki_mirror_backup runs periodically and automatically on the live instance of ITGwiki to create a backup and copy it to the mirror. itgwiki_mirror_deploy runs on the mirror and is triggered by itgwiki_mirror_backup, imports and adjusts the backup to be read-only, then deploys it on the mirror server. Requires rsync and mysqldump.
