I have done some tinkering and made sounds that are too far away completely 
inaudible. This is the original behaviour so it won't give you unfair 
advantages over other players.
Please try out the attached patch and tell me what you think.
There are four variables to play around with now when you start maps with 
devmap (otherwise they're cheat protected).

- s_alRolloff has been changed from 0.8 to 3 which makes for a quicker sound 
falloff.
- s_alMaxDistance has been introduced that gives the distance from where on   
the gain gets scaled linearly to 0
- s_alGraceDistance is new and is the length where this scale to 0 happens
- s_alMinDistance is unchanged but affects the way sound gain changes as well. 

Feel free to test for various settings and if you think the default ones from 
this patch should be changed, tell me. I'd like settings that don't differ 
too much from the original, though.
