1735812 Fix: delay chat acknowledgements instead of spoofing (#3997)
An easy reproduction case is to mute a player using the Social Interactions screen, let them chat, and then send a message. As ViaVersion produces its own acknowledgements, this now does not match with what the client produced and signed its messages with - so the signature will fail verification.
As an alternative, we always pass through the same acknowledgement bit set - and for 'spoofed' messages, we reuse the last one that we received. In the case of the chat ack packet with just an offset, we need to hold back the window by at least 20 messages to ensure we don't start making claims about whether the client saw a message that ViaVersion cannot yet make a judgement on.
- Add handling for some movement related enchantments in 1.20.5->1.21. This requires ViaVersion to be placed on a Paper server (also for efficiency to properly work)
- Fixed entity effect colors for world particles in 1.20.3->1.20.5
- Improve item comparison in some cases when the item tag was empty in 1.20.3<->1.20.5 (by Camotoy, AJ-Ferguson)
- Fixed handling of the hardcore/not set gamemodes in 1.8->1.9 (by LeonTG, EnZaXD)
- Backup original book pages for creative mode clients in 1.8->1.9 (by EnZaXD)
