Stimulates an object when it is attacked by an AI. Uses a MagicZapStim in Thief or Anti-Human in System Shock 2, or the stimulus in the zap_stim parameter. Unless no_zap_sound is set, a sound is played where the target is. One schema is used when the target is the Player, and another for other objects. In Thief the sounds are ghmagic and hit_magic. In System Shock 2 the sounds are dam_sting and exp_cryopsi.
