Renamed HelperFunctions to UnitUtils as this is way more fitting.
Moved GetThreat to UnitUtils.lua.
Added CanDispositionSelf, CanDispositionFriendlies and CanDispositionHostiles to AbilityInfo.
Renamed GetDamageAmplifiers to GetDamageMultiplier.
Added GetDangerRadius for checking how far away I should stand from a hero.
Changed parameters of GetThreat to take only unitSelf and target. This makes the function easier to use but also increases cpu cost by a little.
