[6/7] Enable tox tests in Docker

* Install the python2 dev packages. Update the readme to tell
   people we now download > 200MB of packages, not ~ 200MB.

 * Update the tox.ini file:

    * python3.4 -> python3.5 as that's what's shipped with Ubuntu 16.04
    * Drop Django 1.6, it's not supported by django-request-framework
    * Drop Django 1.7, it seems to break with sqlparse

   If any of these changes are controversial I'm happy to revisit them.
   Also:

    * Pass in the new environment variables for db host and port.
    * Pass in DISPLAY, XAUTHORITY and HOME to fix seleinum tests.

 * Update the entrypoint script to allow you to do --tox and
   --quick-tox in the same way as --test and --quick-test.
   Update the readme appropriately.

That should be django-rest-framework.

I'd like to revise this patch anyway; it seems d-r-f should be pluggable
so we should be able to test on 1.6 without it.

Apparently 1.6 is also shipped with RHEL7.2 so supporting it is important.

And if we're supporting 1.6 we should probably support 1.7 so I'll chase
this down.

Regards,
Daniel
