I've commited your MIME types now, thanks! That sniffing rule however,
doesn't look right to me after peeking into the Matroska documentation,
so I disabled it for now.

They are case sensitive. You would need to add both .mka and .MKA if
you want to catch both (but there is certainly no need to add all
possible permutations :-))

If the sniffer rule is that long, it could possible be higher as well,
but in general, the weight only comes into play if there are files that
fit more than one sniffer rule at a time.

Yes, although not in a nice and formated manner. You can find a short
description of the format in src/kits/storage/MimeType.cpp line 1388
and following.

Contributors are welcome, as always :-)
