- Add a method named ``assert_`` to the DummyTemplateRenderer. This

  method accepts keyword arguments.  Each key/value pair in the
  keyword arguments causes an assertion to be made that the renderer
  received this key with a value equal to the asserted value.

- Projects generated by the paster templates now use the
  ``DummyTemplateRenderer.assert_`` method in their view tests.
