Webkit now returning percentages for more getComputedStyle properties

Strangely, if an element has css 'min-width' value and a css margin value that is a %, in Safari (Version 5.1.7 (7534.57.2)), the returned value for $(element) is the 'min-width' value!

            // A tribute to the "awesome hack by Dean Edwards"
            // WebKit uses "computed value (percentage if specified)" instead of "used value" for margins
            // which is against the CSSOM draft spec:
            if ( ! && rmargin.test( name ) && rnumnonpx.test( ret ) ) {
                width = style.width;
                style.width = ret;
                ret = computed.width;
                style.width = width;

        return ret;

Fix #12088, Safari 5 and more percentages in getComputedStyle

In particular, min-width and max-width are taunting the awesome hack. Closes gh-865.
