Title: Warn about a missing comma after "By default"

**NOTE:** This rule *does not yet work* and I don't understand why. The error can't even be detected in the incorrect example sentence. I hope that you can help me during code review here. My plan is to add followup rules for missing commas after linking adverbs once I get how this works.
