Damage Calculator

The same calculator with some little fixes. Also implemented the suggestions.
The first if statement is the handling of Fairy Aura with Aura Break the second is without Aura Break.
Could change this into something like 
if ((getAttacker().getAbility().equals("Fairy Aura") || getAttacker().getAbility().equals("Fairy Aura")) && type.equals("Fairy")) {
            damageNow = isAuraBreakActive() ?  (damageNow * 2) / 3 : (damageNow * 4) / 3;
}
if it's better readable.
