Two tab dragging fixes for various window managers:
* Reverse the order of enumeration when enumerating all top-level windows. XQueryTree returns the list of windows in bottom-to-top order, while DockInfo expects the windows in top-to-bottom order (ratpoison WM, Awesome WM).
* Extend the enumeration one level deeper for window managers that parent top-level windows into an unnamed real top-level window (ion WM).
BUG=14004
TEST=Extensive tab dragging in the following WMs: Metacity, Compiz, kwm, ion3, xmonad, ratpoison, awesome.
