submit buttons html5 formnovalidate attribute is not respected

[Danthar]

And because of that, a form is still validated even though you mark a submit button with the formnovalidate attribute.
Through reading the source i learned that a 'cancel' css class should be used.

Please extend this functionality to also work with the formnovalidate html5 attribute. (If you want backwards compat). Or better, throw the 'cancel' css class 'hack' out, and only support the attribute.

I already fixed it in my own version. So if you want I can do a PR.
