back-office contributions processed live, but show "Pending (Incomplete Transaction)" in civicrm

In version 2.1.2:

Credit-card contributions created via back-end "Submit Credit Card Contribution" are appearing correctly in transaction list at account.authorize.net, but in CiviCRM the status shows "Pending (Incomplete Transaction)".

However, this patch changes that behavior so that the contribution in CiviCRM shows correctly as "Completed":
