Subject: [PATCH] oggdemux: don't expose Annodex CMML streams any more

This never really took off - it's hardly used anywhere
and deprecated in favour of Kate. Exposing pads just
leads to confusing 'you are missing a plug-in' messages
when people come across such streams. We could still post
the data on the bus for applications to parse.
