[Freeciv-Dev] (PR#12528) draw focus unit on top

["Jason Short" <jdorje@xxxxxxxxxxxxxxxxxxxxx>]

<URL: http://bugs.freeciv.org/Ticket/Display.html?id=12528 >

This patch draws the focus unit in a separate layer from other units. 
This layer is much higher up, so it will be drawn on top of overlays and 
fog (of course the overlay unit should be unaffected by fog).

Eventually the citybar should be drawn at about the same layer as overlays.
