updater
  =======
  
  
  How does it work?
  - creates backup directory under the ownCloud data directory.
  - extracts update package content into the backup/packageVersion
  - makes the copy of the current instance (except data dir) to backup/currentVersion-randomstring
  - moves all folders except data, config and themes from the current instance to backup/tmp 
  - moves all folders from backup/packageVersion to the current version
  - copy old config.php to the config directory.
