feat(social): add friends, party, chat, private mm, trials browser

[EisigesEis]

Summary

• Add friends, party, XMPP, STOMP api.
• Everyone is friends -- a first in this community.
• Trials Browser (open with F7 in-game) allows custom queue. Requires custom hunt id mod on server and client.
• [No Epic Account] stripped from socials (big yikes)

Testing

• Friend shows online status in chat
• (XMPP) Chat works in /all /party /whisper
• (XMPP) Quick emoji works
• (XMPP) Chat shows friend online/offline
• (XMPP) Whisper does not duplicate to own chat
• (STOMP) Friends list shows status refresh of friends without HTTP
• (Party) Create party with 2 clients, disband during mm as leader, reinvite same client as leader (here stale party cleanup should happen).
• (Party) Stale party cleared on server or client restart
• (Party) Promote to leader works
• (Party MM) Members join same server
• (Party MM) Trial Retry works (also works on Trials Browser hunt ids)
• (Party MM) Private queue on client 1 and public queue of client 2 does not mm onto same server.
• Trials Browser queues exact custom trials hunts
• Trials Browser prevents queue spam or queue without leader or in loading screen/trials/escalation
• Trials Browser doesn't crash game in funny ways or memory leak (held together by hopes and dreams :P)

Future work

• Make regular hunt id trials rotate properly instead of random trial or forcing nayzaga on all weeks.
• Persistent support for friend add/remove
• Bake custom hunt ids into dll?
• Replace [No Epic Account] stripping in dll with valid account init
