the access rules, notably about reading and creation. This allows by the way
to remove the hack about the operation in context when subscribing
users on a document.
The new rules on create and read now include user_id, aka the owner of a note
can always create (default value) and read its notes.
Also removed an unnecessary field (current_partner_id), as it was buggy and
unnecessary; view udpated accordingly.
[IMP] mail: removed a hack introduced in saas-3 with the current orm operation
in context to by-pass some access rules when subscribing someone on a document.
