Always check for reservations in orders to select used mail templates no matter if mail gets send after checkout or after payment. Rename ``bda.plone.orders.mailnotify.notify_reservation_if_payment_skipped`` to ``bda.plone.orders.mailnotify.notify_checkout_success`` and use ``bda.plone.checkout.interfaces.ICheckoutSettings`` to check whether notification mail should be sent after checkout has been done. Adopt ``bda.plone.checkout`` interfaces changes in ``bda.plone.orders.common.ICheckoutAdapter``. Rename ``@@reservation_done`` view to ``@@order_done`` and handle displayed heading and text by order state. Use ``OrderData.currency`` instead of ``ICartDataProvider.currency`` in ``bda.plone.orders.common.PaymentData.currency``.
Remove ``bda.plone.orders.common.SKIP_PAYMENT_IF_RESERVED``. Equivalent exists now in ``bda.plone.shop`` controlpanel settings (**Attention** - default value changed to False there).
