(PR#17777) Remove unit homecity

Here is something I always disliked in Civilization II:

Unit homecities (removing this feature would eliminate
fiddling to
reduce shield loss)
Personally I think this feature made little sense. I think
army upkeep
should be from a nation,
pool not a city pool.

IMO MoM did it well. Civilization III also does it ok.

Per mentioned the problem with the current victory condition
being the
destruction of
all units and cities.

Perhaps we could modify the win condition: to destroy all of
a
player's cities and settlers.
