[Freeciv-Dev] Duplicated cities

[Tomasz Wegrzanowski <maniek@xxxxxxxx>]

There was 23 (twenty three, 0x17, dudek tri, dreiundzweizig) duplicated cities
in nation.ruleset.

I pushed this count down to 2 duplicates : Cordoba (.argentina, .spain)
and Thebae (.egypt, .greece).

I also corrected typo in Canadian set (space at start of cityname)
and added a dozen of cities to Argentinians, so they are reasonable now.
