This deprecates the Paper getHighestBlockAt HeightMap APIs now that
Bukkit has added their own. These methods will stick around long enough
for people to migrate. Their API is pretty much the same as ours,
migration should be quick and easy.

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.
