#76 Restoring a backup does not work because of faulty regex

[Jochem Sparla]

Restoring a backup does not work, because the regular expression (regex) in config-backup-managebackups.php is not correct. It should be delimited using '/'.

On line 93:

$rollBackQuery = preg_split("\n\n\n", $fileRollback);

should be

$rollBackQuery = preg_split("/\n\n\n/", $fileRollback);
