CAP mimeType registration

In order to register the mimeTypes for CAP, the recommended process begins with submitting the desired types to an IETF email list for some informal feedback from their end.  I believe the TC should probably approve this before proceeding and we can discuss this and make any recommendations to the TC during the meeting today.  The mimeTypes for CAP would be:  application/edxl-cap+xml application/edxl-cap+json application/edxl-cap+asn1
