[OIDFSC] OpenID Artifact Binding Working Group Proposal

This creates a new direct message type.   I thought extensions were extending the existing messages.

It is probably a grey area.

Other protocols consider this to be a separate protocol binding rather than an extension of the redirect or POST binding.
