Get tests working and make it easy to keep them working (#56)

* Make the page consistent

Above it says `Supports Django 2.0+`
Requirements contradicts that.

* Fixes #53

TEMPLATE_LOADERS is deprecated as of 1.8 and 1.8 is the base version requirement.
https://docs.quantifiedcode.com/python-anti-patterns/django/1.8/migration/template_loaders_deprecated.html

* Add installation instructions.

Partially addresses #48

* Fixing test runs for Django 2.2

* Fixing test runs for Django 2.2

* Tests work on Django 1.8-2.2

Tox implemented to check it.  Travis is next

* Travis, first try

* Trying to get newer python versions

* Tox passes locally on all python versions

* Version py37-G definition was missing

* Added Travis imagery

 =============
 
 There are simple templates files in `templates/`.  You will need to add Django's
-egg loader to use the templates as is:
