title: override what objects.all() returns when using PassThroughManager in django-model-utils?
body: <p>I'd like to use
  <a href="https://django-model-utils.readthedocs.org/en/latest/managers.html#passthroughmanager" rel="nofollow">PassThroughManager</a>. </p>
  
  <p>Example covers how to define custom manager methods, but can't find info on how to change the <em>default</em> queryset, ie. objects.all().  </p>
  
  <p>How can I specify what my objects.all() will return when using PassThroughManager?   </p>
  
  <p>--- edit --</p>
  
  <p>For future readers, 
  django 1.7 seems to have PassThroughManager built-in</p>
