new module to edit website partner fields, in the odoo back office

By default, in Odoo, it is not possible to edit some partner website fields in the
backoffice. It forces user to edit information via website interface,
that is not optimal.

This module adds a 'Website' tab in the partner form view.
It so allows to edit the partner website descriptions fields.
(website_description, website_short_description).
