Launcher/Core: Proxy Client

[SWCreeperKing]

What feature would you like to see?

A client that would be able to interact with the server as 1 connection and can be connected to by an unlimited amount of clients/games

motivation:

• reduce client connections to the server

as a side effect:

• when connecting with a game it (unless you are doing multiple multiworlds at the same time) can remain on a local host port
• games that don't have compressed websockets won't need to worry as much about being cut off
