[Theora] Other extension for Ogg Theora then "ogg"

This is one of those contentious issues.

In fact a .flac file, should only have flac framing in it... no ogg at 
all... there's actually 3 different types of flac files... "native flac", 
which has nothing to do with ogg, "ogg flac classic", the original 
encapsulation of flac into ogg, and "Oggflac 1.0" which is a new 
encapsulation of flac in ogg.

Being in the windows world, i made my directshow filters also accept .oga 
and .ogv (ie to specify audio or video), since many things in windows are 
based on file extensions... one notable thing that's relevant is WMP's media 
library, to classify a file as going in the audio or video section requires 
a file extension to decide.

But note... these are not accepted extensions for these files... nor is this 
recommended by xiph.

If you look back in the mailing list and meeting minutes, i'm sure you'll 
find many long discussions of such things. on one side the file extension 
people, on the other the "file magic" people.
