Crouch Binds & Arrow Swapping

If possible, allowing both crouch and sliding to function on the same key would be greatly appreciated. As far as I've played, crouch seems to override the slide function, and thus you can't reasonably have crouch and slide bound to the same key.

Another minor, but greatly appreciated change would be to arrow swapping. The sound it makes currently is really disturbing, and doesn't well communicate whether or not you have a loaded special arrow.
