WindowServer+LibGUI: Automatically close child windows with parent

Browse source 
If a window has child windows when it's destroyed, WindowServer will
now automatically tear down all of its children as well.

This is communicated to the client program through a vector of window
ID's included with the response to WindowServer::DestroyWindow.

This does feel a little bit awkward, but managing it on the client side
also seems a bit awkward.
