Update from upstream SpigotMC

Abridged: Force close player inventories when they move/interact
This prevents modified clients from using the 2x2 crafting square as permanent storage

Force Close Inventory On Move SpigotMC/Spigot@db78a70788
Only close once, if needed SpigotMC/Spigot@b652de8e7f
Move to interact event closing SpigotMC/Spigot@b5378850d3
Disregard arm swings - racy SpigotMC/Spigot@f86634e280
