Grant "bypass node checkout process" to sponsor organizers and administrators

It's great to automate the sponsorship sales process but often a sponsor will sign up via phone or other means. Currently, Node Checkout won't allow even user/1 to create a sponsor node without first adding it to the cart. The workaround is to add it to the cart and then publish it manually but we should find a better way to do this. The patch at #424886: Permissions to bypass the checkout process will allow a new permission to bypass the checkout process by role. I'm documenting it here for COD users until Node Checkout applies the patch.
