Consider handling Splash damage

[TheGrayAlien]

This would fix certain abilities like Charge, Whirlwind, and Scroll of Lightning. Add a few lines of code to AbilityDamageOverridden after ability.abilityDamage.targetDamage, ability.abilityDamage.critDamage like so

•             , ability.abilityDamage.splashDamage, ability.abilityDamage.critSplashDamage };
  

•             ability.abilityDamage.targetDamage = replacement.Value[0];
  

•             ability.abilityDamage.critDamage = replacement.Value[1];
  

•             ability.abilityDamage.splashDamage = replacement.Value[2];
  

•             ability.abilityDamage.critSplashDamage = replacement.Value[3];
  

Update docs to inform ruleset creators.
