[Docs Bug] Describe return values of CLI

[masi]

Especially in a CI context it is important to know the different (if any) return values for a run of webhint.

The docs say nothing about the them.

Thanks @masi,

In what page would you expect this return codes to appear?

IIRC, currently it's 0 for success and any other number for failure.

I'd appreciate a dedicated CLI page in the docs. None of the pages within the user guide seem a good place for me. But I expected information on return values in the CI sections. The reason is that I wanted to know how to find out if a step using webhint has failed.

BTW, currently the documentation starts surprisingly with the most invloved topic the API. Only now I realied that it order alphabetically.
