AIFunc_ZombieAttack2()

  Zombie "Evil Spirit" attack.

  Character draws the light from surrounding walls (expanding negative light) and builds
  up to the release of a flying translucent skull with trail effect (and beady eyes).

  Spirit should track it's enemy slightly, inflicting lots of damage, removing sprint bar,
  and effecting sight temporarily.

  Speed of spirit is effected by skill level, higher skill = faster speed

  Spirits inflicting AI soldiers should kill instantly, removing all flesh from the
  soldier's face (draw skull under head model, then fade head model away over a short period).
