Instabul (Not Constantinople)

Fun Fact: I am playing as the Byzantines in Civ V, so the default city is Constantinople (which I of course renamed "Instabul" because it had to be done). I just got my second city, which now has the default name of "Constantinople" because I wasn't using that name. :)

When I conquer the Ottomans' "Instanbul" (or if I play as them), I do the analogous renaming, of course. It simply must be done.
