- Add more parameters to the ambient sound things:

Browse source 
* Second argument: Volume scalar. 0 and 128 are normal volume. (Where "normal" is whatever
    it was defined with in SNDINFO.) Other values scale it accordingly.
  * Third argument: Minimum distance before volume fading starts.
  * Fourth argument: Maximum distance at which the sound is audible. Setting either of these to 0
    will use whatever they were defined with in SNDINFO.
