- a few more tweaks of the sound system.

Browse source 
* removed the distance hack for explosions and replaced it with a lowered attenuation. The distance hack combined with the rolloff hack forced these sounds to always be unattenuated, even when at the far end of a level. Now they fade, but much less than other sounds.
* increased the default NearLimit to 6. For some sounds 4 is not enough and this needs a global limit that works for everything.
