This patch introduces the second MenuApplet: Audio. To make this work, menu applet windows now also receive mouse events. There's still some problem with mute/unmute via clicking not actually working, but the call goes from the applet program over IPC to the AudioServer, where something goes wrong with the state change message. Need to look at that separately. Anyways, it's pretty cool to have more applets running in their own separate processes. :^)
