Reworks PR #520 with newest CodenameEngine

[ItsLJcool]

This is still heavily a WIP because I am building a server along-side making this as a template. You can help this PR be merged faster by contributing here as well.

You are more than welcome to also make commits to this PR if you think I fucked something up lol

The idea here is we use HTTP formatting for client recieving and sending, to make it at least somewhat easy to manage and understand, we can't really use real HTTP requests because ofc it's a WebSocket now, so we just send data directly, but just making a standard way of communicating to the Template Server.

You can also disable AUTO_DECODE_PACKETS in the FunkinWebSocket so you just recieve the haxe.io.Bytes directly and manage it yourself, if needed.
