- change how frame namespacing works to be more completely on the WebCore side

        * WebView/WebFrameInternal.h: Remove _setFrameNamespace: and _frameNamespace.
        * WebView/WebFrame.m: Ditto.

        * WebView/WebView.m:
        (-[WebView setGroupName:]): Call -[WebCorePageBridge setGroupName:].
        (-[WebView groupName]): Call -[WebCorePageBridge groupName].
