Docker support and more
Unfortunately this PR is one that spans a few different topics. I had a look over the code and tried to:
- Clean up composer.json, allowing compatibility with PHP7
- Remove the default Symfony tests and create a test structure that we can hopefully use going forward
- Add a Dockerfile with the aim of allowing new users to easily set up the app for local development
- Add a merge request template
No docker support, license had different names, trying to install on PHP7 just failed.
This merge request template for one thing. It should be easier for new contributors to set up locally if using docker. PHP7 should be supported and we have actual tests that cover some of the code.
- Tests pass
