Friendlist & P2P Play Backport

Quick and dirty client mod that backports the "play with friends" feature Mojang shipped in the 26.2 snapshots. The Mojang-hosted friends list plus P2P-over-WebRTC.

How it works

The 26.2 feature is mostly client-side, and the Mojang services that back it work from any logged-in account. So this is a thin re-implementation on top of those same services:

• Friends and presence over REST to api.minecraftservices.com
• Signaling over JSON-RPC/WSS to signaling-afd.franchise.minecraft-services.net
• WebRTC via webrtc-java
• The P2P machinery adapted from the 26.2 snapshot

In theory, it's version independent enough I could make a universal mod that makes it work on any Netty based Minecraft version. Who knows if I can make it work.
