        - cut out a little unneeded bridge code

        * bridge/mac/WebCoreFrameBridge.h: Removed frame name from createWindowWithURL: method
        and changed it to return a page bridge. Also made createModalDialogWithURL: method
        return a page bridge. Removed the mainFrame and webView methods.
        * bridge/mac/WebCoreFrameBridge.mm:
        (-[WebCoreFrameBridge nextFrameWithWrap:]): Use page to get to main frame.
        (-[WebCoreFrameBridge setFrameNamespace:]): Ditto.
        (-[WebCoreFrameBridge frameNamespace]): Ditto.
        (-[WebCoreFrameBridge _shouldAllowAccessFrom:]): Ditto.
        (-[WebCoreFrameBridge _frameInAnyWindowNamed:sourceFrame:]): Ditto.
        (-[WebCoreFrameBridge findFrameNamed:]): Ditto.
        (-[WebCoreFrameBridge installInFrame:]): Ditto.

        * bridge/mac/WebCorePageBridge.h: Added outerView method to replace webView method
        on the frame bridge.

        * bridge/mac/BrowserExtensionMac.mm: (WebCore::BrowserExtensionMac::createNewWindow):
        Update to use a page bridge instead of frame bridge.

        - cut out a little unneeded bridge code

        * WebCoreSupport/WebFrameBridge.m:
        (-[WebFrameBridge webView]): Added. Helper, since the WebCore side of the bridge no longer
        has this method.
        (-[WebFrameBridge createWindowWithURL:]): Removed the frameName parameter -- this is now
        handled on the WebCore side. Also return a page bridge instead of a frame bridge.
        (-[WebFrameBridge createModalDialogWithURL:]): Changed to return a page bridge instead of
        a frame bridge.

        * WebView/WebFrame.m: (-[WebFrame webView]): Change to get the webView from the page bridge
        instead of the frame bridge, since it's a per-page thing.

        * WebView/WebView.m: Removed init method since it just does what the default does (calls
        initWithFrame: with a zero rect).
        (-[WebView initWithCoder:]): Added checking so that if the obejcts have the wrong type
        we will fail gracefully instead of hitting "method not found" and the like.
        (-[WebView setPreferencesIdentifier:]): Fix storage leak. The WebPreferences object was
        not released.
        (-[WebView mainFrame]): Removed excess "return nil".
        (-[WebView _pageBridge]): Added. Helper to let you go from the WebView to the bridge
        from outside the WebView class.
        * WebView/WebViewInternal.h: Put _pageBridge into an internal header.

        * WebCoreSupport/WebPageBridge.m: (-[WebPageBridge outerView]): Added. Replaces "webView"
        as public method to tell the WebCore side about the view everything's embedded in.

        - other cleanup

        * WebCoreSupport/WebPageBridge.h: Removed some unneeded declarations.

        * Plugins/WebBaseNetscapePluginView.m: (-[WebBaseNetscapePluginView loadPluginRequest:]):
        Rearrange code so it doesn't have to get the main frame twice.
