Add step to forbid module imports

[Plunts]

As per #2679, I added a formatter to forbid module imports.

nice feature thanks.

Might include this documentation fixup as well. Should consider to automate this by an annotation or something @nedtwigg, this is kind of easy to oversee (error-prone).

If you want to fix other things: the test-case for forbidWildcardImports is still called removeWildCardImports 😉 Just say a word and I'll change it together with the documentation, I just wasn't sure how clean you like your PRs 😀

thanks for update and kind offer, for me both fine, it seems tiny.

Let ned or someone else make the call, my opinion obsolete.
