* Fix - Order status translation in admin and account page.
* Refactor - Changed the method in which order statuses are stored. Previously, order status was a taxonomy. This caused issues when unique term slugs differed from what we were expecting, and also added additonal overhead to order queries in reports. https://github.com/woocommerce/woocommerce/issues/3064 Order status is now stored as post status - several new post statuses have been added. Order class variables are backwards compatible. The only thing to note (for devs) is that any query must use the order status instead of 'publish' when getting orders and querying by post_status. THe shop_order_status has also been removed.
* Fix - Stop sending line items to Mijireh. Like PayPal, Mijireh struggles with out prices including tax due to rounding errors. Since the validation cannot be disabled, its better to just send the order as 1 item. This will prevent rounding errors and payment failures. Prices excluding tax are unaffected.
