remove screen_current() it was utterly bogus when nscreens > 1. pass a fake client_ctx in the case where there's no client and the kbfunc or mousefunc doesn't need a real one, it just contains the current screen, modify these functions so that they pass down the screen context to their callees. make groups per screen, it's the only way it makes sense in this regard. ok okan@.
