Test: phpstan to use config file (#1448)

* Test: phpstan to use config file

* Use phpstan.neon to config the behaviour instead of using the
  CLI arguments. Much cleaner and more readable.
* Define how to format a .neon file in .editorconfig to ensure
  consistancy.

* Test: .htaccess to forbid access to .neon files
