Chrome warning Input elements should have autocomplete attributes

[weickmanna]

To support password managers, we shall follow these rules: https://www.chromium.org/developers/design-documents/form-styles-that-chromium-understands

Unfortunately, kotlinx.html binding only allows setting a Boolean value for "autocomplete":

    var autoComplete : Boolean
        get()  = attributeBooleanBooleanOnOff.get(this, "autocomplete")
        set(newValue) {attributeBooleanBooleanOnOff.set(this, "autocomplete", newValue)}
