Add support for is<HTML*Element>() for type checking

[Chris Dumez]

Add support for is<HTML*Element>() for casting, while supporting the legacy toHTML*Element() form until the code base is fully ported to the new type checking helper.

This should be on a one line.

It's really a shame we need isHTMLUnknownElement(). It'd be nice if you find a way to remove it.
