Serve `.torrent` files with the `application/x-bittorrent` MIME type
instead of the default `application/octet-stream`. This helps improve
the user experience in some browsers (e.g.: in Firefox, the user is
offered the option to open the file with a torrent application, if
it has one installed).

Remove `.jsonp` as there isn't any convention around the JSONP MIME-type
or the `.jsonp` extension. Also, it seems that, `application/javascript`
is arguably the wrong type to use for JSONP.
