Fix for http://bugs.webkit.org/show_bug.cgi?id=13088 REGRESSION
        (r19761-19779): Copy image no longer includes image address 
        (rdar://5067927)

        writeURL() does not need an isImage parameter. Now that it accepts 
        the types as a parameter, we can just declare the appropriate image 
        types within writeImage and send them to writeURL(). Also, 
        declaring the types twice is what broke this.

        * platform/Pasteboard.h:
        * platform/mac/PasteboardMac.mm:
        (WebCore::Pasteboard::writeURL):
        (WebCore::Pasteboard::writeImage):
