Subject: [PATCH] Fix damage bug - Fixes BUKKIT-5678
If a plugin lowers the damage in EntityDamageEvent while also having damage reduction modifiers,
the entity will in turn be able to receive absorption buff on every hit, making them invincible.

Subject: [PATCH] Revert Bukkit Damage API Behavior
This API is extremely broken and even updated plugins can not adequately restore their intended behavior with the existing API.
Until Bukkit comes up with an adequate solution, lets revert the change in behavior.
New plugins using the API will not error but will also not behave as intended, but there are likely no plugins using this new API.
