rule branch: dev-1622

New input_haspopup_conflict rule logic that Help should support:

        let yesTypes = ["text", "search", "tel", "url", "email", "date", "month", "week", "time", "datetime-local", "number", "range", "color"];
        let noTypes = ["file", "password", "checkbox", "radio", "submit", "reset", "image", "hidden", "button"];

Help was reorganized, simplified (removed redundancies and duplications), and now also includes all the input types
