InGamePacketHandler: queue slots for syncing if they appear in requestChangedSlots
...
this is essentially a prediction without the actual predicted item. We have to sync these regardless of what happens.

InGamePacketHandler: increase max ItemStackRequest actions to 60
...
due to implementation quirks + some unforeseen ways these actions can behave, there can be as many as 53 actions in a single crafting request. This is an edge case, but it has to be catered for.

InGamePacketHandler: relax errors on normal transactions to fix book editing
...
for some reason book edits generate a transaction in addition to BookEditPacket. PM has never used the transaction, and it doesn't pass anyway because CreateItemAction can't be used in survival mode.
However, since the strict validation introduced since ItemStackRequest, this dud transaction now causes the player to get kicked without these changes.

Eliminate final remaining usage of TypeConverter::netItemStackToCore()

instead, we can verify that the held items match by comparing the received ItemStack with the one cached in InventoryManager, which is more cost effective and closes off internal item deserializers to external attacks.

these are now only used for actions done with a closed inventory window. This means that they can only predict the slots of inventory, offhand and armor (total 41 slots) and perhaps include some DropItem actions.

we don't need to check this on a bit by bit level if the integers are the same.
this saves 2-3 microseconds per packet on my machine, which doesn't sound like much, but it adds up when there are lots of players.
