templater: rename .render(mapping) to .renderdefault(mapping) (API)

I'm going to add templ.render(t, mapping) and templ.generate(t, mapping) in
place of stringify(templ(t, **mapping)) and templ(t, **mapping) respectively.

.. api::

   The ``render(mapping)`` method of the templater has been renamed to
   ``renderdefault(mapping)``.
