- The ``settings`` object emitted a deprecation warning any time

  ``__getattr__`` was called upon it.  However, there are legitimate
  situations in which ``__getattr__`` is called on arbitrary objects
  (e.g. ``hasattr``).  Now, the ``settings`` object only emits the warning
  upon successful lookup.
