Title: Fixing XMLSecurity so it works with the StarfieldTMS IdP

Namespace info wasn't being passed to REXML::XPath.first calls when
trying to find the CanonicalizationMethod elements. This was causing the
wrong c14n method to be used for xml responses sent from our IdP
resulting in mismatched digests and a failure to validate.
