PulseAudio hotkeys script

I've been using volumeicon for a long time, to enable the audio hotkeys on my laptop. But the problem is that if you plug in a USB or bluetooth headset, it doesn't automatically switch to it as the default. You'd have to kill the service and restart it.

So I wrote a script that can offer me all the same functionality, and just mapped my audio hotkeys in my WM.

Thought someone might find the source useful.
