WOO-833

* Added more explaining docblocks during coding, so that inspections will be clearer.
* Continued cleanup of RCO-stuff. Also removed the getTermsByRco-method.

* Adjusted method icons for cards and logos etc so that the checkout won't crash during the render.
* Removed filter for v2.2-icons (getMethodIconDeprecated).
* Removed SOAP-specific method for specific types.
* Disabled most of the code (not removed) in payment_fields that should utilize ecoms formfields.
* Adjusted some functions that was showstopping the checkout (getMethodIconByContent).
* Moved functions around in WooCommerce-class, so they are easier to find (for now).
* Prepared transients for non-cache-instances (WOO-816).
