[REF] audittrail: monkeypatch the openerp.service.model functions.
Instead of inheriting from object_proxy, audittrail now wraps the original openerp.service.model functions. This potentially means it is possible to further wrap them (whil inheriting from the object_proxy was feasible by only one module at a time). bzr revid: vmt@openerp.com-20130131160625-dd43wk7q7y1jbwxg
