Server-based netcode and AntiLead

[suhbruh]

Finish the server-based netcode that crawly has made to have real-time discerning between sword hits/rockets/grenades/hitscan weapons/etc. NAT - server sided hit detection.

Current Anti-lead issues: Packets sometimes get lost/malformed that can happen once every few 100 packets with UDP. This leads to showing HIT in P2P anti-lead but still does not reduce target's HP/AP. Sometimes, there is no HIT but the target's HP/AP is reduced.
