Invisible targets

[Cyruz143]

These are really handy for mission makers if you want to get the AI to engage various objects without having to force manual firing (doFire) etc.

Currently in the base game there are B_TargetSoldier O_TargetSoldier I_TargetSoldier

Suggesting we add B_TargetVehicle B_TargetArmor O_TargetVehicle O_TargetArmor I_TargetVehicle I_TargetArmor

Let me know if this is something worth looking at and I'll see if I can have a go at writing something up.

Just tested the default base invisible units: B_TargetSoldier O_TargetSoldier I_TargetSoldier

AI don't see them or engage them so it'll need looking at from scratch.
