Remove the attack from wall turrets.

Wall turrets/towers have more HP & are cheaper than free-standing
towers, and have no build restriction distance. Their attack, while
limited, is still high when garrisoned, and this makes them awkward to
balance and is poor design in general.
This removes their attack capability entirely, and standardizes the rest
of their statistics.
