hw/xwin: Use _NET_WM_NAME for window titles in multiwindow mode

Browse Source 
Use _NET_WM_NAME in preference to WM_NAME for window title

Update window title when _NET_WM_NAME property changes

We should always have been doing this, but some qt5 examples only set
_NET_WM_NAME, so now it's become more important...
