This change implements a mechanism to retransmit orders if some of the order's selected regions do not confirm transmission in due time. It adds a worker to repeatedly check the orders and determine if they need retransmission. Such orders will be added to a new table named tx_retries. The tx_start function now first checks if there are regular new paid orders to transmit. If not, it will check the retransmission table and retransmit an order from there if one is available. This patch also introduces a new order state called "retranmission". The order enters this state while waiting for retransmission.
