From 76c37ce3acc7a4af0271c7535d4a33042f7749b5 Mon Sep 17 00:00:00 2001
From: Dan McGee <dan@archlinux.org>
Date: Tue, 24 Jul 2012 09:35:55 -0500
Subject: Replace deprecated direct_to_template() with render() shortcut

Now that Django actually provides a concise way to use a RequestContext
object without instantiating it, we can use that rather than the old
function-based generic view that worked well to do the same.
Additionally, these function-based generic views will be gone in Django
1.5, so might as well make the move now.
