players don't cut ahead of the store during auctions

[vaylen]

In the original MULE, if a player decides to buy from another player selling to the store (or to sell to another player buying from the store), he simply moved his line to meet the transaction and all units bought and sold would involve him instead of the store. Currently moving up to the transaction line doesn't allow you to cut in front of the store. It only gets to you when that transaction is finished and if there is another transaction.
