There are other cases where we can't just query a library
like GStreamer.  Take, for example, File Roller.  It can
handle *LOTS* of archives formats, but only if you have
the command line tools for those formats installed.

What if we just added a MimeTypeExec field which gives
a command to run.  This command should give a list of
MIME types that are actually supported.

Then file-roller.desktop could have this:


And Ryhthmbox and Totem and such could call some
command supplied by GStreamer.
