form-nonce id with multiple forms.

Regarding forum post: https://getgrav.org/forum#!/plugin-development:form-nonce-on-multiple-form
The page does not pass html validation when more than one form is displayed on a page. This is because each form contains a hidden input of <input type="hidden" id="form-nonce" name="form-nonce" value="********" />.
ID's must be unique and therefore the id of form-nonce breaks validation as it appears more than once.

Yes, technically that's not valid according to HTML specs, however it does still work and doesn't effect functionality. We'll get this sorted soon.
