Martin Gräßlin a4fed7188c Use the first client as entrance to the focus chain if no active window 
The recently used mode of TabBox uses the active window as the entrance
into the focus chain. If there is no active window it does not find any
Clients. To solve this issue the ClientModel now uses the first entry
of the focus chain in case there is no active window.
