Spigot might skip chunk registration changes in removeEntity
which can keep them in the chunk when they shouldnt be if done
during entity ticking.
Should fix some cases where "Entity is still in another chunk section"
Related to #1223
Vanilla logic checks unload queue and overwrites if its in it.
we're triggering this if a chunk unloads, and reloads immediately in same tick.
Added check for unload queue to not treat as duplicate
Also fixed the config setting not even loading
Should fix#1280
Citizens hijacks entity map, and im guessing under the right conditions
the result might actually be null during entity creation
Pre the cache patch, the id is looked up on save, so it was fine.
Now, if its null and the save ID is requested, we will try to look
it up again and cache it if found.

Should fix Vanilla bugs
Minecraft is saving invalid entities to the chunk files.
Avoid saving bad data, and also make improvements to handle
loading these chunks. Any invalid entity will be instant killed,
so lets avoid adding it to the world...
This lets us be safer about the dupe UUID resolver too, as now
we can ignore instant killed entities and avoid risk of duplicating
an invalid entity.
This should reduce log occurrences of dupe uuid messages.
Also reduce the logging spam overall.
Setting the flag updates the spawner's delay which stops the spawner from trying to find a new spawn position each tick efter the event was cancelled/aborted which makes it usable for mob stackers/mergers and other plugins that don't actually want any mob to spawn in the spawner cycle but keep the overall behaviour close to vanilla.
This might slightly effect existing plugins that use this event but I doubt anyone really relied on this behaviour, the only possible use case that I can think of is cancelling the event until you find a suitable position in your plugin... and this should be handled by the plugin itself by cancelling and spawning at the position manually.
Cleaned up some implementation notes to use existing Vanilla method for some things.

Due to a bug in 2e29af3df0
which was added all the way back in March of 2016, it was unknown (potentially not at the time)
that an entity might actually change the seed of the random object.
At some point, EntitySquid did start setting the seed. Due to this shared random, this caused
every entity to use a Random object with a predictable seed.
This has caused entities to potentially generate with the same UUID....
Over the years, servers have had entities disappear, but no sign of trouble
because CraftBukkit removed the log lines indicating that something was wrong.
We have fixed the root issue causing duplicate UUID's, however we now have chunk
files full of entities that have the same UUID as another entity!
When these chunks load, the 2nd entity will not be added to the world correctly.
If that chunk loads in a different order in the future, then it will reverse and the
missing one is now the one added to the world and not the other. This results in very
inconsistent entity behavior.
This change allows you to recover any duplicate entity by generating a new UUID for it.
This also lets you delete them instead if you don't want to risk having new entities added to
the world that you previously did not see.
But for those who are ok with leaving this inconsistent behavior, you may use WARN or NOTHING options.
It is recommended you regenerate the entities, as these were legit entities, and deserve your love.
Added code that refreshes the player's skin by sending packets with a special order, telling the client to respawn the player and re-apply the game profile

This is useful for project developers switching back and forth between
1.12.2 and 1.13 so we can have our IDE automatically use the
current version we are working on for included mc-dev files.
This won't happen anyways if the user has
"skip ticking for entities in chunks scheduled for unload" turned on,
but if they don't, protect from this instant killing the entity to
keep it vanilla in behavior
a player may teleport away, and trigger instant despawn
Spigot had code that returned early in chunk add/remove methods.
This was causing our code added to set current chunks and counts to
be skipped over if the entity was default not persistent but made persistent.
This was the source of many issues
Fixes#1208
When interacting with entities with an item, the client will assume
the interaction is successful, and update the held item on the
client. However, if the interaction is cancelled on the server side,
the client will still mistakenly remove/replace the item in hand.
Examples for this are milking cows with a bucket or dyeing sheep.
The bucket is replaced with milk and the dye removed from inventory.
Refresh the player inventory when PlayerInteractEntityEvent is
cancelled to avoid this problem.
The adjacent blocks of doors, double plants, pistons and beds need
to be updated manually from the server when cancelling a block break
from a player, as it otherwise causes the other parts to disappear
on the client.
This is already done for doors but only for the BlockBreakEvent,
not for PlayerInteractEvent. Move the code to a common method
and also handle the other blocks in similar ways.
The extra buffer used to decode the strings sent by the client
in the legacy ping protocol was never released. However, creating
an extra copy of the buffer just to decode it to a string isn't
actually necessary: We can just call toString() directly on the
original buffer.
Additionally, free the buffer in handlerRemoved() to handle cases
where the client never sends enough bytes to form a valid legacy
ping request.
Closes#1197
While this really undoes a lot of the desired performance gains avoiding chunk lookups,
we sadly have to accept this because we are seeing lots of bugs with entities.
Allows you to increase how far to check for a safe place to respawn
a player near their bed, allowing a better chance to respawn the
player at their bed should it of became obstructed.
Defaults to vanilla 1.
In many places where we simply want the current chunk the entity
is in, instead of doing a hashmap lookup for it, we now have access
to the object directly on the Entity/TileEntity object we can directly grab.
Use that local value instead to reduce lookups in many hot places.
