update CampaignCreateConfirm.php

Added DELETE privilege... parser stats UNDO needs it.  Added global FILE
privilege since reading log and group files (and writing group files)
needs it.

Also put backticks around DBname... to cure a mysterious problem where
some commands that worked for the other three example campaigns did NOT
work for the  1916 campaign.  All numeric database names apparently are
not a good idea, but the backticks get around the problem.  I can now
create an all numeric DBname without a problem.
