        Disallow copy from new password fields

        * WebView/WebHTMLView.m:
        (-[WebHTMLView _canCopy]): Now also calls across the bridge to ask if it mayCopy.
        (-[WebHTMLView _canCut]): Calls _canCopy now.
        (-[NSArray validateUserInterfaceItem:]): Calls _canCut when validating the "Cut" menu item.
         This used to call _canDelete (which used to be the same as _canCut), but now _canCut also checks _canCopy.
