[Makhil]

it's not the support that needs hard coding, it's the state of relations between alliances.
- If 2 alliances decide to be allied: they can't attack each other, they can def each other with eta bonus
- If 2 alliances declare war: they can't def each other
- If 2 alliances are neutral: they can attack each and they can defend with no eta bonus

The support rule is obsolete, when 2 alliances cooperate, it is ridiculous to expect them to set up joint attacks but not defense, especially when it's a block vs block war, with all 3 alliances of 1 block waving a single gal.
