Partner Contact address default

This module adds three new fields on the partner form: Shipping address, Invoice address and Default contact. You can fill them in on a company or on an individual contact.

• On a contact, a "Force addresses" section appears where you can force the contact, delivery and invoice address for that specific contact. If you leave the fields empty, Odoo's normal behaviour applies.
• When a document asks for an address (for example a delivery or invoice address), the module first looks at the address set on the partner itself, and if it is empty it falls back to the one set on the related company (the commercial partner).
• By default the selectable addresses are limited to the partner's own child contacts and to contacts of the right type (delivery, invoice or contact).
• In Settings, a new option lets you lift that restriction so that any contact can be chosen as default delivery, invoice or contact address.
• If a contact that is used as a default address is archived, the module automatically clears it from the partners that referenced it, so no archived contact stays as a default.

The module touches res.partner, res.company and res.config.settings, and adds a setting under the partner autocomplete option in the general settings screen.
