Add script to set the PulseAudio sink for the current window.

This binding is set to <C-z>a. It creates a dmenu prompting the user to
select which output device the current application should send audio to.

In the future I might create an analog for input devices, but as things
stand, I change input so much more infrequently that pavucontrol is
probably fine for that.
