[boskid][1.1.53] artillery-projectile can be a place result

[Honktown]

If the artillery-projectile is added to a place_result of an item, the game immediately errors when the item/ghost is brought out of the inventory to place.

763.823 Error Util.cpp:83: Can't create artillery-projectile, target not specified.

Expectation: "not allowed as place_result" after data

Thanks for the report. It is now fixed for 1.1.54.
