[Openal] 3D Sound and moving Listener

Standard drill on this -- what audio device(s) are you using, what is 
the revision of openal32.dll and wrap_oal.dll in your system directory, 
revisions if you have an nvopenal.dll or a ct_oal.dll in your system 
directory, etc... 

Please try your app out with multiple audio devices -- at least "Generic 
Software" and "Generic Hardware"...  At this point, these problems seem 
to wind up being with broken DS3D drivers being used by the "Generic 
Hardware" device -- switching to "Generic Software" will probably fix 
the issue, and updating your DS3D drivers may fix the GH-device issue.

> P.S: On a different topic, it would be nice if the AL specification would mention that stereo sources are computed differently than mono sources.

I'll make sure the spec is explicit on this point in the next revision.
