Form_Field_Hidden doesn't render properly

[DarkSide666]

/atk4/lib/Form/Field.php, class Form_Field_Hidden, function render()

HTML output of hidden form field somehow gets HTML sanitized and as result show "HTML code" of element in page.

This is how you can reproduce this bug:

class page_index extends Page {
    function init(){
        parent::init();
        $p = $this;

        $f = $p->add('Form');
        $f->addField('hidden','test field'); // This shows as [and]lt; input name="..." type="hidden"...etc [and]gt;
    }
}

When I remove render() function overwrite from class Form_Field_Hidden at all, then output renders correctly.
