Fix java fallback support on browsers that don't natively do ogg.

TMH was comparing the mime type 'video/ogg; codec="theora, vorbis"'
to 'video/ogg; codec="theora,vorbis"' when checking if cortado
could play the video. The mime checking code is not very robust
and doing string equality comparisions. As a result in the different
spacing, TMH determined that the java cortado applet could not
play theora videos.

This should significantly improve the number of desktop MSIE
and Safari users who can play our videos.

A future todo would be to make TMH more robust about how it
checks mime types.
