-----------
Recognize webm and matroska files. See also Bug 23888
Currently all webm files are stored as video/webm. It is not possible to detect
wether this file is an audio file without using a full parser. This is why We
should
really move mime and mediatype accessors to the MediaHandlers.
Using video/x-matroska for MKV files. There is no official mime for MKV (though
the
webm isn't official either, but everyone is already using it apparently).
