Stop Attack

[Alz]

There are a few problems with people being able to cancel attacks. Whilst chaos is also a bit unfair at times, I feel being able to cancel an attack would be worse.
Imagine a large incoming, you move troops to defend your city. Attacker sends in his spies just before he lands to get a report. Does not like what he sees and then cancels the attack. That would get really annoying. Nit would become the normal way to attack as well I think.
