util.array: Fix equality metamethod in Lua 5.3 Lua 5.2 only used the __eq metamethod if both operands have the same __eq, but Lua 5.3 will pick one from either operands that has one as long as both are tables. This results in array() == {} and all sorts of odd behavior, including array() == util.json.null. <MattJ> I think [array() == {}] should have the same semantics as {} == {}
