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.
