Whenever an item is added to or removed from the player's ContainerStore, that player sends a PlayerInventory packet with just that addition or removal.
This eliminates all the unnecessary packet spam related to oversized PlayerInventory packets that had existed in one form or another since the initial implementation of inventory sync in 1b259e2d33
Additionally, move booleans from BasePlayer to LocalPlayer when they are only needed on the client, and make the usage of the isReceivingQuickKeys boolean consistent with the new isReceivingInventory boolean by having them both in the processors of their associated packets.
For a long time, whenever a PlayerInventory packet was sent, it contained all the items in the player's inventory, because that's how Koncord originally implemented it and I always had too many other priorities to go back and rework it.
From now on, clients only send PlayerInventory packet with the one item added or removed, with the single exception being trading with merchants, where the entire inventory is still sent for the time being.
Unfortunately, disabling clientside deletion of summons and items that can be picked up requires extra work on actors and inventories respectively, to avoid buggy situations.
