[IMP] website_contract

[IMP] website_contract
- removed already-defined res.partner fields, using dependency towards website_partner;
- fixed references/<partner_id>/ that was buggy;
- cleaned a bit references controller;
- fixed customer template that was crashing;

website_partner: added website_published onto the partner form view, to be able to
change it directly in the backend
