Subject: [PATCH] Adding no window decorations patch

This patch sets the _MOTIF_WM_HINTS property on the st window which
will allow the window to be drawn without window decorations if the
window manager supports it.

In GNOME and KDE this should allow the window to be drawn without a
title bar at the top.

In dwm if the decoration hints patch is applied then the st window
should start without a window border.
