Lots of work to update the model for users, passwords, membership, testing,

and the REST API.   A highlight of the merged changes:

* The REST API now has a /users top-level URL under which user information can
  be accessed, and new users can be created.
* IUsers now have a unique `user_id` which is evident in the REST API.  Under
  testing, these uids are predictable, but otherwise, they're entirely random
  but guaranteed to be unique.
* IUsers now have a `created_on` attribute.  Like `user_id` these are
  predictable under testing, but otherwise reflect the actual date.
* User passwords are now 'encrypted' (hashed) as defined by the config file.
  - new mailman.cfg variables password_scheme and password_length
* IMember gets a `user` attribute which is a convenience for getting the IUser
  associated with the member.
* mmsitepass is gone:
  - creator_pw_file
  - site_pw_file
* Improved test initialization and its hook into zc.buildout.
