 - Add a RedirectingFormIdentifier plugin.  This plugin is willing to
   redirect to an external (or downstream application) login form to
   perform identification.  The external login form must post to the
   "login_handler_path" of the plugin (optimally with a "came_from"
   value to tell the plugin where to redirect the response to if the
   authentication works properly).  The "logout_handler_path" of this
   plugin can be visited to perform a logout.  The "came_from" value
   also works there.

 - Identifier plugins are now permitted to set a key in the
   environment named 'repoze.who.application' on ingress (in
   'identify').  If an identifier plugin does so, this application is
   used instead of the "normal" downstream application.  This feature
   was added to more simply support the redirecting form identifier
   plugin.
