- fix <rdar://problem/4246096> REGRESSION links to named anchors don't scroll to the right place (4825)

        This is really just a better fix for 4233844. Also consolidated manual-tests/scrollToAnchorWithNewline.html
	and the test case from Bugzilla bug 4825 into manual-tests/scrollToAnchor.html.

        Test cases added:
        * manual-tests/scrollToAnchor.html: Added.

        * khtml/xml/dom_nodeimpl.cpp:
        (DOM::ContainerNodeImpl::getUpperLeftCorner): when calculating scroll position, skip child nodes of the anchor
        if they do not have text boxes.
