DRY template rendering decorator update

Based fully on [snippet 1929](http://www.djangosnippets.org/snippets/1929/) **The update is:** It checks to see the view returns an instance of HttpResponse and returns that rather than trying to render it. This allows you to return something like `HttpResponseRedirect('/')`, or use a normal `render_to_response` to use a different template. *Also updates cleandict as per comment on original snippet* In this case the 'render_template' decorator assumes there is a myview.html template. this keeps things simple and you DRY. Hope it helps.
