This needs some improvements, because:
1) Sometimes the cell authority sends the death animation too late and a different one gets played on the other clients
2) There is probably a simpler check that can be done for position changes during a death animation.
Previously, it was possible for a Container packet to clear all equipment slots for an actor without the actor's authority then sending an equipment packet to correct that, due to packet loss or sudden disconnection, leading to actors not wearing any equipment as soon as they acquired a new authority.
This ensures that newly initialized LocalActors will now autoEquip.
Previously, a Container packet with a SET action for an actor would clear their entire InventoryStore, also clearing all of their equipment slots. The actor's authority would then autoEquip new equipment for the actor, but that new equipment would not actually get sent to the other players. As a result, they would see the actor fighting with hand-to-hand attacks, while also not actually wearing anything despite being rendered as wearing the same clothes and armor as before.
This commit makes the actor's authority resend the actor's equipment as soon as the Container packet has caused the autoEquip to happen.
Previously, certain errors early in the program's execution – such as an attempt to use two different packet processors for the same packet ID – would not be displayed because of a crash when attempting to get an uninitialized mwmp::Main in the Engine's destructor.
When determining actors siding with someone, also check the team members of DedicatedPlayers, not just those of the LocalPlayer.
Don't set players as each other's hitAttemptActor if they are team members.
Don't run startCombat() for DedicatedPlayers who get attacked.
Revert 9502d84a9cb99028f76f7fd2e05f9193ca66561 because the creature graveyard solves more problems than it causes. Only have the authority of a cell send deletion packets when a summon despawns.
Summoning is one of the least multiplayer-friendly systems in OpenMW and really needs to be redone serverside.
Previously, receiving a Container packet about an actor with a previously initialized listener who was currently located in an unloaded cell crashed the game.
Previously, creatures with fast attack animations would have their attack updated right after being started, which happened so quickly that it prevented the attack start from actually being sent by the client.
