I have tested that the Replenishing Feature still works as expected.
Lootable API's that now have Bukkit equivalents are now deprecated.
Bukkit Changes:
f0f33981 SPIGOT-1936: LootTable API
CraftBukkit Changes:
c0df4b82 SPIGOT-1936: LootTable API
This enables us a fast reference to the entities current chunk instead
of having to look it up by hashmap lookups.
We also store counts by type to further enable other performance optimizations in later patches.
