[theora] Marketing stuff

[Ivo Emanuel Gonçalves]

I only have on issue so far with the marketing page: calling it Ogg
Theora.  It's just Theora.  Save everyone a lot of headaches by
avoiding the confusion that always arise from the word "Ogg".  I
recall this sad remark on the FLAC list from someone who didn't want
to compile FLAC with Ogg, because he didn't want "any of that lossy
crap".  Ogg, the lossy format.  Sigh...

Also, with the whole deal that Theora may be used outside of Ogg (e.g.
Matroska, RTP), calling it Ogg Theora gives developers the impression
that it works solely within Ogg, which is not true.

It's not "AVI Xvid".  It's not "MKV H.264".  Why should it be "Ogg Theora"?
