WIP Remove Scrutinizer, Add Coveralls

Scrutinizer has been a source of problems for a long time. False positives, unavailability, not open source, irrelevant complexity flags.

I am a bit concerned because Scrutinizer sometimes seems to run even without a yaml file. We shall see.

I do still want coverage reports. Instead of uploading them to Scrutinizer, I will try Coveralls, which is used by PhpWord.
