[PATCH v2 0/4] Remove support for Django 1.6

[Finucane, Stephen]

> Django 1.6 is no longer supported, neither with feature bugfixes nor
> security fixes. Additionally, Django 1.6 does not support the use of
> Django Migrations, necessitating the continued use of manual SQL
> migration files. Drop support for Django 1.6 thus encouraging users to
> move to Django 1.7 or, ideally, Long Term Support (LTS) release 1.8.
> 
> v2: Remove Django < 1.7 blocks

Have discussed this with Jeremy and this is good to merge. In the future, we will attempt to support any currently supported version of Django. This will mean ensuring Django 1.9 shortly after its release in December, and Python 3 is supported for Django 2.0.
