Deprecate Attr.nodeValue / Attr.textContent

Deprecate Attr.nodeValue / Attr.textContent as those are no longer present
in DOM:
http://dom.spec.whatwg.org/#interface-attr

This behavior is consistent with Firefox (confirmed with version 28), which
also prints a deprecation warning when accessing those 2 properties on an Attr
object. The warning message promotes the use of Attr.value instead.
