django 2, use template views, specify default_config

[devkral]

Hello, I rewrote some of your code for django 2 support and cleaner solutions. My changes are:

• add django 2 requirement and some fixes
• use templateviews instead of own implementations (can use context stuff now in serviceworker.js)
• add content_types
• update README.md
• add PWA_APP_FETCH_URL (later for my own serviceworker.js default implementation)
• add default_config in __init__.py (sometimes required for finding the apps config) I can seperate the commit request if wished

I didn't provide backward compatibility for django 1.11. Shall I change this?

[devkral]

I will split out the serviceworker implementation in an own package (the django url tag makes the special parameter (PWA_APP_FETCH_URL) superfluous). See: https://github.com/devkral/django-pwa-batteries

Hi @devkral, my apologies for taking so long to get to this. I'll try to get it reviewed within the next week. Thank you for taking the time to make these updates!

[devkral]

no problem

I'd like to pull in your django-pwa-batteries work since I think people will mostly want both. Would you be okay adding it to this module? And I'd also like to provide support to Django 1.11+ since that's the current LTS.

sry, github ate my answer. I am ok with the pwa_battery stuff being pulled in. But be aware it is beta. It needs some tests and most probably bugfixes.
