Ambient sounds

Here you go everybody. I changed a few sounds out to legal sounds, and added an attributions list. I intend to keep working on it.

This works with the new sound sets.

Edit: This is not like tilesets where you have to be able to draw. Anybody can go to freesounds.org and pick new sounds. I will get this up on Github so everyone can help.
