        Fixed a problem where the webview passed to the EditorClient wasn't valid yet.

        * WebCoreSupport/WebEditorClient.h:
        (WebEditorClient::setWebView):
        added webview setter

        * WebCoreSupport/WebEditorClient.mm:
        (WebEditorClient::WebEditorClient):
        add default constructor

        * WebCoreSupport/WebFrameBridge.m:
        (-[WebFrameBridge initMainFrameWithPage:frameName:view:]):
        use [page webView] since _webview isn't valid yet
        (-[WebFrameBridge initSubframeWithOwnerElement:frameName:view:]):
        use webview setter on editorclient
