Support switching system sounds to the current output device

[deviantintegral]

I can use the following to match the "Selected sound output device" option in Sound preferences:

SwitchAudioSource -t output -c | tr '\n' '\0' | xargs -0 SwitchAudioSource -t system -s

It would be nice if there was an option to do this right in the app.

This is a helpful tip for anyone who needs to do this. :)
