---- Files affected:

freeciv/common game.c game.h
freeciv/server ruleset.c savegame.c stdinhand.c

---- Log message:

Introduce new server variable citymindist which will overwrite the
ruleset variable min_dist_bw_cities if set to non-zero. This allows
non-smallpox games without modifying the ruleset.

Patch from Karl-Ingo Friese <kif@xxxxxxxxxxxxxxxxxxxxxxxxxx>.
