Composer Tag Support

[docgnome <doc...@do...>]

Just started using cmus and I love it other than one thing...
Lack of support for the composer tag. I see on the wiki that someone
is working on this and was wondering if that is still the case. Wikis
can sometimes get out of date is why I ask.

If it is, if that developer needs any help, I'd be happy to lend a
hand.

If it isn't true, I'd be willing to take a crack at it.
