For the new plug-in API, we need to pass a WebPluginContainer to the plug-in view upon creation. The is owned by the WebFrame. To make this all work, I had to move the WebCore plug-in and java view constructors to WebBridge from WebViewFactory since WebBridge has the frame.

        * khtml/khtml_part.cpp:
        (KHTMLPart::createJavaContext): New APPLE_CHANGES around the java context constructor so we pass the part.
        * kwq/KWQKHTMLPartImpl.mm:
        (KWQKHTMLPartImpl::createPart): call the bridge to create the view
        * kwq/KWQKJavaAppletWidget.mm:
        (KJavaAppletWidget::KJavaAppletWidget): save the context
        (KJavaAppletWidget::showApplet): call the bridge to create the view
        * kwq/WebCoreBridge.h:
        * kwq/WebCoreViewFactory.h:
        * kwq/khtml/java/kjavaappletcontext.h: made constructor take the part
        * kwq/khtml/java/kjavaappletwidget.h: ivar for the context

WebKit:

        * WebCoreSupport.subproj/WebBridge.m:
        (-[WebBridge requestedURL]):
        (-[WebBridge viewForPluginWithURL:serviceType:arguments:baseURL:]):
        (-[WebBridge viewForJavaAppletWithFrame:baseURL:parameters:]):
        * WebCoreSupport.subproj/WebViewFactory.m:
        (-[WebViewFactory fileButton]):
        (-[WebViewFactory pluginsInfo]):
