- Added a NULL pointer check to A_Fire() and copied the target to a local

variable inside A_VileAttack() so that if P_DamageMobj() destroys the
  target, the function will still have a valid pointer to it (since reading
  it from the actor's instance data invokes the read barrier, which would
  return NULL).
