Subject: [PATCH] Add completions for Pulseaudio's pacmd

To implement this mostly as a wrapper around pactl, we add the list of
commands for this to that. It's 90% the same anyway. (This means that
`pactl suspend ` will complete files instead of commands like `pactl
banana ` would, but neither is correct)
