Django-compat

https://github.com/arteria/django-compat is the initial version of a for- and backwards compatibility layer for Django 1.4.+ to 1.7.+ . Consider django-compat as an experiment based on the discussion on [this reddit thread](http://www.reddit.com/r/django/comments/2jrr4l/whats_the_best_practice_to_provide/). Let's see where it goes. Feedback and contribution are greatly appreciated!
