--[[
supported_nodes
This table stores all nodes that are compatible with the wrench mod.
Syntax:
	[<node name>] = {
		lists = {"<inventory list name>"},
		metas = {["<meta name>"] = STRING,
			["<meta name>"] = INT,
			["<meta name>"] = FLOAT},
		owned = true,
		store_meta_always = true,
	}
	owned - nodes that are protected by owner requirements (Ex. locked chests)
	store_meta_always - when nodes are broken this ensures metadata and 
	inventory is always stored (Ex. active state for machines)
