[IMP] website_sale: Enable billing/delivery address on checkout process

Purpose
=======

Address management is not clear. If you use the eCommerce, you can set 2 different addresses (billing / shipping) in the checkout process while the related access right group is not activated (group_sale_delivery_address). So you don't see such dates in the backend, which leads to potential conflicts with customer (if the delivery address is different).

Functional spec
===============

- Hide shipping stuff in checkout if option is not activated:
- When eCommerce is installed, group_sale_delivery_address should be activated automatically.
- If you uncheck it from user access (already it is disable in sale settings) , it has to disappear in both the bakend AND the frontend.
