2.9.4  
* added some more gateway functions to use in future gateway development    
* added 'REFUNDED' as payment_status  
* bugfix: when using mail() or wp_mail() as mail delivery, external plugins (notably "delivery by post/zipcode") were not able to override "To" email address although they should have been able to do so
