Use json fields where applicable

Resolves #298

How well does the code work when querying rows after the migration goes through?

[sgordon16]

I'm not sure I understand your question, but you can now do a query like this for example:

CRUDEvent.objects.filter(object_json_repr__0__model="app.user", changed_fields__has_key="name")

This will give you all the records of users that had their name changed.

@jheld Just following up on this. Are there any issues with this?

[jheld]

Probably not. but we are in the middle of a potential issue on the latest pre-release and I'm hesitant to add more big changes like this. I think 1.3.8 series would be a good fit.
