hidden attributes

[AndreiMaz]

there is this hidden input element that uses the new HTML5 "hidden" attribute (hidden="hidden"). Please keep in mind that this attribute will not going to work in IE9 and IE10 browsers which nopCommerce still supports. In those browsers the element will go visible. Of course if nopCommerce is about to drop support for IE9 and 10, then this won't be an actual problem.
