Report that a factory chain is built at the location nearest the factory chain

[neroden]

While working on merging patches from standard into extended, I found a place where standard would benefit from doing what extended is doing. This has been the code in extended for years, because extended can't use the code in standard.  But this code doesn't rely on anything in extended.  It works, and it's cleaner.

Instead of looking at get_target_cities, this reports the city which the factory is, in fact, actually closest to after it's built.

That code was even used for consumers, so it is even more consistent, thanks. Incorporated in r11242
