Support for Django integration [https://github.com//pull/266]

I am excited to announce ChatterBot's new support for direct integration with Django. Django plays a huge role in the Python community and a tremendous number of developers choose to use it for their projects and applications. I believe that enabling developers to use ChatterBot easily in their Django applications will open numerous new doors for what we can create.

ChatterBot 0.4

This is a fairly major release with many changes breaking backwards compatibility.

Introducing Input & Output adapters

IO adapters have been divided into two new modules (input adapters and output adapters).
This change makes it possible to write less code by being able to mix and match different
types of inputs with different types of outputs.

Improved documentation

Lots of new documentation has been added. Check it out! http://chatterbot.readthedocs.io/
