        GMail Editor: Operations that use drop down menus blow away the selection

        * WebView/WebHTMLView.m:
        (-[NSArray maintainsInactiveSelection]): Maintain an inactive selection
        when resigning as first responder if the selection is editable
        or if the WebView tells us to.
        * WebView/WebView.m:
        (-[WebView maintainsInactiveSelection]): Just because a WebView is
        editable doesn't mean selections inside subframes will be.  Return
        NO by default.
