Allow ACS SpawnDecal zoffset and distance args to be fixed point

Browse source 
The wiki currently says they should be fixed point but the code
currently treats them as integers. Given that they are placed with
double precision horizontally, it is odd that the same precision
cannot be applied vertically. Changing this would break existing maps
so add two flags to support both types.
