Comment 4 for bug 1298411

The question is how it should be fixed:
1. Use defeat: You only have to destroy the warehouses (maybe add one for the yellow player)
2. Check if all military buildings are destroyed instead of check if defeated.

1 is good because new users are told that an enemy is defeated when his warehouses are destroyed.
2 is good because it is not needed to change the text (in the mission the command is: "Destroy all forces").

If you tell me which way you prefer and if I allowed, I will do it ;)
