chg: use rich address partial in checkout with add/delete support

Replaces the simple address radio list in the checkout page with the
richer ``Shop.Customers.partials.addresses`` partial already used on
the profile edit page.  Customers can now choose among existing
addresses, add a new one on-the-fly, or delete an address directly
from the checkout flow.
