Title: Moderate Proxy Models

`SerializedObjectField._serialize` was raising an `AttributeError` when serializing a proxy model because the `_meta.parents` dictionary contains a `None` value since there is no field pointing to the parent. I've added tests to demonstrate the problem along with the fix. There is still a problem with serializing proxy models on Django versions prior to 1.4 due to https://code.djangoproject.com/ticket/17717. These tests are marked to be skipped on earlier versions. The test skipping introduces a new test dependency of `unittest2`.
