Fixed _NET_CLIENT_LIST and _NET_CLIENT_LIST_STACKING publishing on 64bit oses
to convert Window Ids to 32bit. Fixes window lit not showing in gnome-panel
and other GNOME apps.
Added handling of _NET_WM_STATE_FOCUSED as per Extended WM Hints spec.
Added corresponding ClientMessage handling.
Fixed handling of AS desktop number to GNOME desktop number translation. That fixes
window focusing using GNOME pager and window list.
