siege

Placing an enemy city under siege should be easier:
a city should not be able to work a square that is reachable by an enemy
unit in 1 turn.
this means that entering the area around the city so as to be able to
displace another player's city work should require a declaration of war.
alternatively, displacing worked squares requires declaration of war.
(squares covered by friendly units can be worked)
