Legacy ping support (#4062)

* Detection of protocol versions before 18w47b

* Refactor old_protocol_versions into protocol_version

* Ping servers closer to how a client of an instance's version would ping a server

* Allow pinging legacy servers from a modern profile in the same way a modern client would

* Ping 1.4.2 through 1.5.2 like a Vanilla client in those versions would when in such an instance
