[PATCH v2] pactl: Add a command for setting the default sink/source.

[poljarinho@xxxxxxxxx (poljar (Damir Jelić))]

This adds two new commands to pactl:
    set-default-sink
    set-default-source

This command has been part of the native protocol for a long time,
no reason not to expose it in pactl.
