Fix ESLint Exceptions

Type of issue

Code quality improvement

Description

This is a tracking issue for code quality improvements. The .eslintrc files include many exceptions which are not actually good ideas (see the comments in those files).

Anyone who has time is encouraged to fix code which violates them, and, if possible, remove those exceptions. Everything which eslint could --fix automatically has already been taken care of. I recommend removing at most one quality issue per PR, to keep the diffs manageable.
