[Freeciv-Dev] (PR#9397) remove rectangle_iterate

["Jason Dorje Short" <jdorje@xxxxxxxxxxx>]

<URL: http://rt.freeciv.org/Ticket/Display.html?id=9397 >

This patch removes the unused rectangle_iterate.  Not only is it unused 
but it won't work for hex topologies, since (as may seem obvious) there 
are no rectangles on a hexagonal grid.
