 - If `Spawner.AttackImmediately` is set to true, spawned aircraft will assume attack mission immediately after being spawned instead of waiting for the remaining aircraft to spawn first.
 - `Spawner.UseTurretFacing`, if set, makes spawned aircraft face the same way as turret does upon being created if the spawner has a turret.
 - `Spawner.RecycleRange` defines the range (in cell) that the spawned is considered close enough to the spawner to be recycled.
