Allow moving/resizing undecorated X windows
* exwm-manage.el (exwm-manage--manage-window): Do not manage undecorated floating X windows (set in _MOTIF_WM_HINTS). * exwm-floating.el (exwm-floating--start-moveresize) (exwm-floating--stop-moveresize, exwm-floating--do-moveresize): Allow moving/resizing undecorated X windows with _NET_WM_MOVERESIZE client message.
