        <rdar://problem/6828894> - Facebook photo uploader applet broken on Leopard only

        In r41568 we started adding a default codebase attribute to <applet> tags if they didn't specify one
        themselves.  Leopard's Java plug-in mishandles this case and fails to load code for the applet.

        The spirit of r41568 can be maintained by removing the "default codebase" piece and only performing
        the canLoad() check if a codebase was actually set on the applet tag.

        * html/HTMLAppletElement.cpp:
        (WebCore::HTMLAppletElement::createRenderer): Don't create a default codebase attribute.

        * loader/FrameLoader.cpp:
        (WebCore::FrameLoader::createJavaAppletWidget): Only perform the canLoad() check if the codebase was set.
