portmidi: New package in version 217.

This uses a patch from Gentoo to disable Java support for now, as it is
not needed for supporting Mixxx (which is the package I'm preparing).
Hopefully, the patch will be applied upstream so we can safely drop it
here.

mixxx: New package in version 1.11.0.

Compiles fine on linux i686 and amd64. Adding myself as maintainer, even
though I'm not using the package by myself, but a friend is using it for
DJing from a NixOS live system I'm maintaining.

miro: New package, version 6.0.

I actually had this breeding in my nixpkgs overrides for a year and only
recently took the time to fix it and thus revive my video feeds :-)

The package uses a patch which is removing the dependency on gconf and
switches to storage within a shelve in ~/.miro/config instead.
