Customizing UI sounds

[ger]

I don't recall ever getting a too far sound, but some of the sounds are so subtle that it's easy to miss them—the chest sound, for instance. I know I've heard it many times, but I also know I've missed it just as often. Good thing it's hard to miss seeing the chest itself. (Maybe I should change that to Homer shouting "Woo hoo!" doubt I'd miss hearing that hehe)
