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

WOO-843

* Added option for enabling/disabling the entire gateway (Not the plugin, just the gateway functions - meaning basic functions, payment methods etc). To compare, this is the enabled-setting that also resides in Presta/Magento and allows the module to be enabled without interfering with "aftershop requests" etc.
* Added "update_option" for controlling the gateway through wc-payments tab (with unexpected results).
* Updated Data::isEnabled to the new settings controls.
* Cleaned up gateway-list to handle gateways properly, based on how payment methods should be listed.
* Removed legacy-filter (getAllowResursRun).
* Added redirect helpers from "payments"-list (adminGatewayRedirect).
* Booleans for isEnabled added.
