        Renamed khtml::Selection to khtml::SelectionController since it's far more
        than just the selection position itself. Also renamed WebSelectionDirection
        WebSelectionGranularity and their constants to have a WebBridge prefix so they
        don't collide with possible public enums with a similar purpose.

        * ForwardingHeaders/editing/SelectionController.h: Added.
