title: list_editable and widgets
body: <p>When using <a href="https://docs.djangoproject.com/en/dev/ref/contrib/admin/#django.contrib.admin.ModelAdmin.list_editable" rel="noreferrer">list_editable</a> in <code>ModelAdmin</code>, is there any way to change the widget used for the editable fields? I can't find anything in the documentation. Seems like this would be something you'd be able to customize.</p>
