Numerous fixes to entity related changes
While it wasn't really "broken" before, if plugins use NMS
(which they really should't be) and mess with entity management
themselves, and get it wrong, they could ultimately corrupt our
state expectations.

I've been unable to reproduce any issues locally, but these changes
are the result of me analyzing the code pretty deeply and seeing
about how to make it more durable to abnormal usage.

Any servers seeing oddities, please run with -Ddebug.entities=true
and send me any logs triggered.

Subject: [PATCH] InventoryCloseEvent Reason API
Allows you to determine why an inventory was closed, enabling plugin developers
to "confirm" things based on if it was player triggered close or not.
