This fixes item position desync (MC-4) by running the item coordinates
through the encode/decode methods of the packet that causes the precision
loss, which forces the server to lose the same precision as the client
keeping them in sync.
Adds config options for modifying the spawn rates of Wandering Traders.
These values are all easy to understand and configure after a quick read of this
page on the Minecraft wiki: https://minecraft.wiki/wiki/Wandering_Trader#Spawning
Usages of the vanilla WanderingTraderSpawnDelay and WanderingTraderSpawnChance values
in IWorldServerData are removed as they were only used in certain places, with hardcoded
values used in other places.
Uses correct setPositionRotation for Entity teleporting instead of setLocation
as this is how Vanilla teleports entities.
Cancel any pending motion when teleported.
This forces the despawn counter to start ticking regardless of
state after the arrow has been alive for 200 ticks (10 seconds)
instead of getting stuck in a never despawn state (bubble columns,
etc).
Adds an option for maximum exp value when merging orbs
Adds ExperienceOrbMergeEvent
Fired when the server is about to merge 2 experience orbs
as entities. Plugins can cancel it if they want to ensure experience orbs do not lose important
metadata such as spawn reason, or conditionally move data from source to target.
Fixes an issue where the stacked count was not taking into account
for mending repairs and when merging with spigot's merge-on-spawn
logic

This notably fixes the newest "Donkey Dupe", but also fixes a lot
of dupe bugs in general around nether portals and entity world transfer
We also fix item duplication generically by anytime we clone an item
to drop it on the ground, destroy the source item.
This avoid an itemstack ever existing twice in the world state pre
clean up stage.
So even if something NEW comes up, it would be impossible to drop the
same item twice because the source was destroyed.
If the playerdata contains an invalid world (missing, unloaded, invalid,
etc.), spawn the player at the spawn point of the main world.

Will not run if:
Max entity cramming is disabled and the max collisions per entity is less than or equal to 0.
Entity#isPushable() returns false, meaning all entities will not be able to collide with this
entity anyways.
The entity's current team collision rule causes them to NEVER collide.

This allows you to solve an issue in vanilla behavior where:
* On easy difficulty your villagers will NEVER get infected, meaning they will always die.
* On normal difficulty they will have a 50% of getting infected or dying.
Item entities only have their gravity ticked every 4 ticks when on ground.
Fix that and also remove Spigot's arbitrary tick skipping. It's a terribly
cheap way of getting extra performance that doesn't really work at all.
This patch adds an option "disable relative projectile velocity", which, when
enabled, will cause projectiles to ignore the shooter's current velocity,
like they did in Minecraft 1.8 and prior.
If a player is falling, for example, their shooting range will be drastically
reduced, as a downwards velocity is applied to the projectile. This prevents
players from saving themselves from falling off floating islands, for example,
as a thrown ender pearl will not make it back to the island, while it would
have in 1.8.
While this could easily be done with plugins, too, there are multiple problems:
P1) If multiple plugins cancel the velocity by subtracting the shooter's velocity
from the projectile's velocity, the projectile's velocity would be different.
As there's no way to detect whether the projectile's velocity has already been
adjusted to ignore the player's velocity, plugins can't not do it if it's not
necessary.
P2) I've noticed some inconsistencies, e.g. weird velocity when shooting while
using an elytra. Checking for those inconsistencies is possible, but not as
efficient as just not applying the velocity in the first place.
P3) Solutions for 1) and especially 2) might not be future-proof, while this
server-internal fix makes this change future-proof.
Expose an entities spawn reason on the entity.
Pre existing entities will return NATURAL if it was a non
persistenting Living Entity, SPAWNER for spawners,
or DEFAULT since data was not stored.
Additionally, add missing spawn reasons.

Entities must be dismounted before teleportation in order to avoid
multiple issues in the server with regards to teleportation, shamefully,
too many plugins rely on the events firing, which means that not firing
these events caues more issues than it solves;
In order to counteract this, Entity dismount/exit vehicle events have
been modified to supress cancellation (and has a method to allow plugins
to check if this has been set), noting that cancellation will be silently
surpressed given that plugins are not expecting this event to not be cancellable.
This is a far from ideal scenario, however: given the current state of this
event and other alternatives causing issues elsewhere, I believe that
this is going to be the best soultion all around.
Improvements/suggestions welcome!
