        - finished frame traversal cleanup
        http://bugzilla.opendarwin.org/show_bug.cgi?id=6293

        * WebCoreSupport.subproj/WebBridge.m:
        (-[WebBridge childFrames]): Removed (this was unused)
        * WebView.subproj/WebFrame.m:
        (-[WebFrame _removeChild::]): Moved to FrameTraversal category.
        (-[WebFrame _childFrameCount]): New frame traversal method to avoid
	getting the count from the array directly.
        (-[WebFrame _appendChild:]): Factored out the parts of addChild: that
	seem directly relevant to adding a child.
        (-[WebFrame _removeChild:]): Moved to FrameTraversal category.
        (-[WebFrame _detachChildren]): Don't deallocate children array because
	there's no particular need to.
        (-[WebFrame _setDataSource:]): make the assert use _childFrameCount
        (-[WebFrame _opened]):
        (-[WebFrame _checkLoadComplete]): Instead of checking all frames starting
	from the main frame, check this frame and all ancestors. If a resource
	for a frame completes, that con only possibly finish loading for that
	frame and its ancestors, not any other frame in the tree.
	(-[WebFrame _recursiveCheckLoadComplete]): Removed, no longer needed.
        (-[WebFrame _childFramesMatchItem:]): Get child frame count in the new
	approved way.
        (-[WebFrame _internalChildFrames]): removed
	(-[WebFrame _addChild:]): Use _appendChild: for most of the work.
        (-[WebFrame _generateFrameName]): Get child frame count in the new
	approved way.
        (-[WebFrame _stopLoadingSubframes]): Use new frame traversal mechanisms,
	upon further consideration there's no need to copy part of the frame tree here.
        (-[WebFrame findFrameNamed:]): Remove extra braces.
        (-[WebFrame childFrames]): Make a new array using the frame traversal methods.
        * WebView.subproj/WebFramePrivate.h: Remove some methods.
        * WebView.subproj/WebMainResourceLoader.m:
        (-[WebMainResourceLoader didReceiveResponse:]): Do _checkLoadComplete on the current
	frame not the main frame (before there was no difference and now the new version is
	what is desired).
        * WebView.subproj/WebView.m:
        (-[WebView _finishedLoadingResourceFromDataSource:]): Remove stray space
        (-[WebView _mainReceivedBytesSoFar:fromDataSource:complete:]): Remove stray spaces
	and update FIXME comment.
        (-[WebView _receivedError:fromDataSource:]): Remove stray space
