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] Fix client rendering skulls from same user
See: https://github.com/PaperMC/Paper/issues/1304
Changes the UUID sent to client to be based on either
the texture payload, or random.
This allows the client to render multiple skull textures from the same user,
for when different skins were used when skull was made.
