Check for _NET_WM_CM_Sn before trying to install ourself as composite manager

xcompmgr should check for a selection owner of _NET_WM_CM_Sn before taking ownership on it, so clients watching for selection ownership
changes won't be disturbed.

Try to report current composite manager name

The attached patch try to read NET_WM_CM_Sn owner's NET_WM_NAME (or WM_NAME) property and display it or if not possible report its window id.
Remarks: metacity and kwin currently don't set a window name for
NET_WM_CM_Sn owner, but xcompmgr and compiz do. This should be added
to wm-spec.
