Add audiopause(on/off) command

If you have unfocus pause off, and unfocus audio pause off, then this command will go into effect.
When it's set to on, the audio will pause when you unfocus the game. When it's set to off, the
audio will not. This is different from the setting, and gets saved to the save file.
