Well of Suffering item drop control (#1388)

* Added a new DamageSource for the Well of Suffering
Added an event handler for death through Well of Suffering
Added a config option to enable (true) or disable (false) Well of Suffering Mob drops.

* Moved the DamageSource creation to RitualManager
Renamed the new DamageSource to "RITUAL_DAMAGE"
DamageSource "RITUAL_DAMAGE" is now used by RitualForsakenSoul and RitualWellOfSuffering
Added death message string for "RITUAL_DAMAGE" for en_US and de_DE

* Cleanup, removed the ability to damage entities in creative mode (creative mode should be considered as having infinite health, the rituals only damage mobs anyways).

* Update GenericHandler.java
