Update: FullServerDemo - try to handle transient(not in the savefile) Entities - Record an entity snapshot once per demo chunk if sending specific messages - Positions, Flags, RPC(both server-sending and recieving) - DemoTransientEntities are not sent if we've sent an entity snapshot via Entities message during active chunk - Fixed not handling demo messages that can have 0 connections associated with it - Fixed incorrectly aborting on "unknown" message type when types are related to demo-specific messages. In theory this should allow us to avoid missing entities scenarios when playing back, which helps with determinism. But the server-recieving-RPC scenario needs more work - we record the transient snapshot after we recorded an RPC from the client, so I need to implement look-ahead in demo playback (or do what client demo playback does and index the demo). Tests: on Craggy in editor recorded a full server demo where I'm looting a wood-collectible. During playback it spawns, but doesn't get removed
