EFFECT_CHANGE_DAMAGE should be taken in account when calculating battle damage

[edo9300]

If a card like Dark Ruler no More change all the damage to 0, it will also set the battle damage to 0, so in field::calculate_battle_damage when the various EFFECT_CHANGE_BATTLE_DAMAGE are checked, any EFFECT_CHANGE_DAMAGE that is also valid for battle damage should be taken in consideration, otherwise while attacking under the 0 damage of dark ruler no more, Duel.GetBattleDamage will return a non 0 value, even if that attack will deal no damage. @DailyShana
