Django REST framework

This is a fork of django-rest-framework v2.4.x, just renamed to rest_framework2 so it can installed alongside rest_framework to ease the porting from 2.4.x to 3.x.

1. pip install djangorestframework2
2. find and replace all imports of rest_framework with rest_framework2
3. pip install djangorestframework
4. Start porting your code view by view.
