Updated Upstream (Bukkit/CraftBukkit), deprecate SentientNPC API
Upstream has added the equivalent of our SentientNPC API, with exception to the EnderDragon.

We've added Mob to the EnderDragon, and our SentientNPC API should behave the same.

Vex#getOwner has been deprecated and a replacement Vex#getSummoner has been added using Mob.

However, since 1.13 is not production ready, SentientNPC API is subject for removal in 1.13.1 since
1.13 API is not compatible with 1.12.

Please move to the Mob interface ASAP.

This update has not been tested by PaperMC and as with ANY update, please do your own testing

Bukkit Changes:
c5ab54d8 Expand GameRule API
ab9a606c Improve entity hierarchy by adding Mob interface.

CraftBukkit Changes:
29e75648 Expand GameRule API
50e6858b Improve entity hierarchy by adding Mob interface.

Subject: [PATCH] Prevent Saving Bad entities to chunks
See https://github.com/PaperMC/Paper/issues/1223
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.
