Title: Set field size of ps_orders.shipping_number to 64

In table PREFIX_orders, set the field "shipping_number" to varchar(64) instead of varchar(32), so that it is the same as the field "tracking_number" in table PREFIX_order_carrier. As far as I could understand it, those two fields are the same data.
