Add autocomplete to forms

[aerni]

Add autocomplete attributes to the form builder: https://developer.mozilla.org/en-US/docs/Web/HTML/Attributes/autocomplete

This could be implemented the same way you already do with the input type.

The 'input type' config option is not special for form blueprints, where as I think this would probably need to be? (unless there's a case for it...)

Yes, autocomplete only makes sense for forms. What's the case for input_type on a regular blueprint? I can't think of one either.

I know I've used it before in the case of a URL, where it will warn the user if it isn't formatted correctly (eg. they type something that's not a URL)
