I am not sure why you are adding these methods to the delegate. It doesn't look
like code in TCW is having to call them. Rather, it's all high level browser
code.

Since RenderViewContextMenu, which will call GoBack and GoForward, uses some
delegates instead of Browser itself. So I added these methods here. But
currently I don't think here is appropriate. TabContents seems more appropriate
to have these methods, because it already has OpenURLFromTab, which is a kind of
navigation method. So I moved these functions to TabContentsDelegate.
