        Implemented isId as specified by DOM Level 3. See detailed description below.
        https://bugs.webkit.org/show_bug.cgi?id=5578

        Added isId property and implementation:

        Replaced instances of HTMLNames::idAttr with Element::idAttributeName()
        for the reason that id attribute name could be customized to a different
        string other than "id". A test case is associated to each code change.
