Models Moving Plan

[David Edmundson]

Merged!

Current task is now to get to a point where we don't depend on any of
the old models.

An important discussion to have is what we do with the roles.

We need to:
1) work out what we actually want/need, and not just copy from tp-yell
2) find a way to do roles properly.

We need the basic roles, we need roles from the basic contacts list
model, both grouping models, and my (as yet unpublished) identity
model which tracks ongoing conversations.. .and this all needs to be
extensible.

I don't know how best to do this

_and_ we need to share roles with kpeople.
