I haven't seen many libraries that permit automatic unmutes that persist through logouts, so I endeavored to make one for those who're interested.
I also put in a ShadowMute feature, for those who want to mute players without their knowing.
Feel free to take it and mess with it as much as you want.
DISCLAIMER: I purposely made this a bit wordy, with a bit more code than necessary so that it's easily manipulable.
