Comprehensive box-sizing fix.  This patch changes all form controls to
        have the right box-sizing values (text fields and text areas actually only
        use border-box in quirks mode now, and image buttons never use border-box).

        Tables are supposed to use border-box box-sizing as well, but that's a scary
        enough change that I'm saving it for a separate patch.
