Aaron Kimbrell 5832567bc4 fix: trigger volume effects go out as live sent them 
A trigger's SetPhysicsVolumeEffect is "type,amount,x,y,z,use distance,
min,max". In live phantom physics constructions:
- the direction has the amount as its length: "Push,50,0.91,-0.34,-0.22"
  went out as 45.68, -17.07, -11.04. DLU multiplied the arguments as
  they were, so a direction that isn't a unit vector pushed harder;
- a zero direction ("Repulse,150,0,0,0,true,25,100") is no direction;
- the distances go out when use distance is "true" ("true,150,175" as 1
  and 175, "true,20,50" as 1 and 50) and not when it is "1"
  ("Push,40.0,0,1,0,1,20,50"). DLU never wrote them.
LWOPhantomPhysicsComponent::Deserialize (0x00c34db0) reads the two
distances as floats and keeps the least of the min and 1, and a max of at
least that.

Seven arguments no longer read an eighth.
