Followers can now be partners or channels. Partners following a document
will receive needaction, as previously. However people can follow documents
through channels. Members of a channel are able to listen to a stream
of messages using the channel. Those messages do not create needaction

too much notifications. For interesting documents subscribing with its
partner will create notification.
message_follower_ids fields is udpated. It is now a many2many to
mail.followers, not to res.partner anymore. A subscription can be either
a partner (partner_id) or a channel (channel_id).

the access rules, notably about reading and creation. This allows by the way
to remove the hack about the operation in context when subscribing

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.

in context to by-pass some access rules when subscribing someone on a document.
