SPWW2 handicaps vs AI

[Mobhack]

Predicted MG fire lanes for defence at night. USA "recon by fire".

Z-fire is far less effective than plotted indirect fire, and deliberately so. A 60mm mortar section firing its HE in plotted indirect fire will be about twice as deadly as if you pointed it at a random hex and fired in direct area fire mode (Z fire).

Still, we are looking at possible fixes for this - perhaps charging 2 ammo per shot, or 2 shots per z-firing.
