Another small addition for mpc so that you can toggle the
crossfader.

p.s. I noticed the use of (cdr (assq 'etc ...)) throughout and
guessed that was because mpc predates alist-get but if there is a
preference I can change it to match the other mpc-toggle-*
functions.

Err. I guess it should have a NEWS entry too.

Sorry for the flood.

No, no, `alist-get` is fine, thanks.
