Paper/Spigot-Server-Patches/0231-Add-ArmorStand-Item-Meta.patch
Zach Brown aac051e35b
Redo API for vanilla CanPlace and CanDestroy NBT 
Now properly serializes and deserializes, is factored into hashcodes and
equality checks, etc

Deprecates the old Material based system and replaces it with a new one
based around NamespacedKeys and NamespacedTags. This allows the API to
extend beyond vanilla and Material enum based properties to datapack
based tags and elements.

Fixes GH-1635

Subject: [PATCH] Add ArmorStand Item Meta
This is adds basic item meta for armor stands. It does not add all
possible metadata however.
There are armor, hand, and equipment types, as well as position data
that can also be added here. This initial addition should serve a
starting point for future additions in this area.
Fixes GH-559
