[SELLING] Confirm the order

When an order has been received, an actor has to confirm it.

A player has a choice of positive or negative confirmation, of which only 'confirm the order' results in a positive signal to the sender of the order. When you choose to not confirm the order, no shipment will be sent to the customer. In some scenarios of the game, a certain percentage of the total order value might be charged to the supplier if the order is cancelled at this stage of the transaction process. The latter thus depends on the specific scenario of the game.
