Add soc.views.simple containing (initially) two simple template views. templateWithLinkName() is a view that can replace most public() read-only views. errorResponse() is a view that renders an error page for out_of_band.ErrorResponse exceptions. Also, change response_helpers.respond() to accept keyword arguments to pass to http.HttpResponse(). (errorResponse() makes use of this new respond() feature.)
