Subject: [PATCH] Ignore Dead Entities in entityList iteration
A spigot change delays removal of entities from the entity list.
This causes a change in behavior from Vanilla where getEntities type
methods will return dead entities that they shouldn't otherwise be doing.
This will ensure that dead entities are skipped from iteration since
they shouldn't of been in the list in the first place.
