- Add two new APIs to the ``repoze.bfg.configuration.Configurator``

  class: ``add_adapter`` and ``add_utility``.  These, respectively,
  perform the same functions as the ``registerAdapter`` and
  ``registerUtility`` functions of a ZCA registry.  They were added to
  allow for a more consistent testing API for applications that make
  use of the ZCA directly.

- Cause the ``adapter``, ``utility``, and ``subscriber`` ZCML
  directives to use a ``Configurator`` instance and associated
  configurator APIs rather than a ZCA registry directly.
