mpd: output to localhost
was previously outputting to a socket, but candybar doesn't seem to want
to work with that (it defaults to localhost). Additionally, most
programs require manual configuration which can be kind of annoying,
especially since the only reason mpd was previously outputting to a
socket is because it was in the Arch wiki example.
