OpenSpy Core: reconstructing GameSpy online services

OpenSpy Core reconstructs GameSpy online services as separate processes communicating through HTTP, AMQP, and Redis. Its QR service handles ASCII V1 and binary V2 formats, while server browsing supports legacy and enctypex variants. Other implemented services cover NAT negotiation, presence, account search, game statistics, chat, and selected EA FESL traffic.
