Thanks @timgraham. Sorry for the delay in getting to this. Things have been busy for me but I have some breathing room these days.

I did already notice that it was going to be hard to support all of the officially supported version of Django when 2.0 comes out. Dropping support for the older versions seems like a good solution. I plan to make a 1.6 release soon and then I'll look more closely at this PR.

@timgraham This looks good. It just needs to be rebased and it can be merged. There are a couple of new fields added since this PR was submitted so they'll need to be updated as well. The failing tests should point you in the new fields. Let me know if you'd like me to rebase this instead - it's not a problem.

Done
