refactor for independent test dirs (#7)

* make it so that the actual tests can be moved anywhere, for example in abra recipe repos
-> major refactoring with pytest test discovery magic

* create RUNNER_DICT dynamically with importlib
-> none of the tests are hardcoded, more tests can be added by placing a folder

* autoload fixtures with pytest plugins

* add URL fixture to navigate on web pages. Includes url parser based on python urllib to generate correct links

* fix nextcloud setups and tests

*  add email groundwork with imbox
