application/pgf as MIME type for PGF grammar

After consulting with Krasimir Angelov, and checking the naming convention for MIME types, e.g., we have decided to file the content type of PGF grammars published by MOLTO as application/pgf. The GF community should discuss and decide whether to register the MIME type officially with IANA,


alternative MIME types

we could of course apply for the vanity tree

Registrations for media types created experimentally or as part of
products that are not distributed commercially may be registered in
the personal or vanity tree.  The registrations are distinguished by
the leading facet "prs.".
