Changing the way Error.php logs error messages in the Habari event log.  Previously, it was trying to pass along the error ID of a failed DB  transaction, but this wasn't a definied severity. Since these log  entries are errors (they're generated in error.php!), they should have a  severity of 'err', which is one of our defined severities.
