Grenade/explosive damage fading

[Victor]

I do like the curve with that more. I modified them to make sure they drop below one at range.
...

Instead of "rlin: max/((max-1)*x+1)", try "rlin: max/(x+1)" (x is distance/range).

At the maximum range, half the damage is dealt (quarter for the square, eighth for cubic, etc.) and it continues to infinity. Use the code to set the cutoff when the damage falls below 1.
