Options Menu is now working

You can turn off music or SFX, although the only SFX currently affected is the death sound

Since there are many sources of audio coming from random objects, it seems that turning off the bgm turns off all audio. I couldn't find a nice fix for turning off audio from some sources unless I add specific objects to the script.

If we really need to, I can make a sound manager for each audio object I guess. It's hard to find them sometimes though, since the audio is attached to random trees and stuff.
