* Fixes mapstart and random arcade machines (#53958)
Randomly generated arcade machines were getting random boards and initing properly, but they weren't re-built as the appropriate subtype.
This oversight has been remedied. A new subtype has been created for random arcade machines which exists purely to pick a random circuit then create a machine from that circuit's build path before returning that it should be qdel'd.
This new subtype has been appropriately regex find-and-replaced into all maps.
