tornevalls-resurs-bank-payment-gateway-for-woocommerce

Mostly for WOO-716

* Removed further timeout-checks, as they can't be used with ecom2. Also cleaned up further getConnections.
* Updated further docblocks.
* Updated getPaymentId to reflect how we want to handle order references in future (we should probably rename it too).
* Updated setOrderLines to reflect the way orderlines should be handled via ecom (Beware and take height for the RCO traditional way!).
* Started to correct process_payment and preProcessOrder (Remember-RCO note).
* Updated plugin to NOT use setOrderLines when handling MAPI (for the sake of RCO).
* Updated and cleaned up processSimplified (a bit) to prepare the MAPI request.
* Fixed a bunch of customerType-enums (ecom2) and how we handle customer types (including fixes for getAddress).
* Removed order_id_type from config, as we will use a natural way to create order id's (as long as it is not RCO).
* WOO-750: Removed processHosted to simplifiy the flow handling.
* Splitted up orderline handler for simplified and rco.
* setOrderLines for RCO is now getOrderLinesRco.
* resursDefaultReference should no longer be necessary if we handle references properly.
* Disabled setMetaData for customer id for now (See task 810).
* Finalized getMapiOrderProductRow which is the generic handler for all products.
* Added getMapiCustomOrderLine for all custom order rows that is not a product.
* Updared getFromProduct to include helpers for both MAPI and RCO.
* process_payment/preProcessOrder: disabled setProperPaymentReference as we try to avoid using external id's.
* Restored processResursOrder from recent changes when MAPI was a module. API-types is no longer relevant.
* Updated: getOrderLinesMapi.
* Added: getMapiArticleRows, getMapiFeeRows, getMapiShippingRows, getMapiCouponRows,
