  Log Message:
  -----------
  Restore a `_unauthorized` hook on the response object. (#112)

* Restore a `_unauthorized` hook on the response object.

This is used as a hook by PluggableAuthService.

* Also call `_unauthorized` if application code raised Unauthorized.

Rather than raising an Unauthorized HTTP exception, we have to trust
and use the possibly modified response instance. This means you can
not register exception views for Unauthorized, same as in Zope 2.13.

* Add changelog entry.
