This will add options to the Mainland and African Plains random maps that will place allies more closely together (the algorithm used for the playerPlacementMultiArcs function was written by @Jammyjamjamman (who freely and ethically admits to pinching code from other sources)). The playerPlacementMultiArcs (Beside Allies) placement also added to the Frontier and Ambush random maps (which already use the TeamPlacement option specified in their corresponding json files).
