From Martin Mathieson:

- adds application/xpidf+xml as a media type known to be xml
- appends /xml to the protocol column (as SDP does).  It would be nice
to append the top-level element, or the name taken from a matching DTD,
but this will do for now (at least its a short name).
- corrects the help text for the preference.  I can see that it is
registered as a heuristic for "http", "sip" and "media"

I've also included a slightly updated version of reginfo.dtd (RFC 3680)
for the dtds folder.
