PlayerDeathEvent#getItemsToKeep
Exposes a mutable array on items a player should keep on death.

This allows a cleaner method to implement "Keep certain items on death"
than how plugins currently do it in that it never removes them in first
place, so its safe if the player logs out/server is shutdown before respawn.

Example Usage: https://gist.github.com/aikar/5bb202de6057a051a950ce1f29feb0b4

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.
