Python -> Django app

Needs an idiomatic Django backend example using best practises.

Now that Django dev has experimental [Python 3 support](https://www.djangoproject.com/weblog/2012/aug/19/experimental-python-3-support/), I think it should be using Python 3. Well, Django 1.5 is far from released, but when it is, people are going to want examples on how to build Django with Python 3. Python 3 is the future, so why not.

I've thought about there being two identical apps, one in Python 2 and one in Python 3, but I ended up not suggesting it, since they would be too similar. Django abstracts away most of the mess for you.
