the second time the slot is synced, there is no prediction, so the slot update isn't associated with a request anymore. This causes subsequent requests in the same packet to fail, since the dependency request ID isn't associated with the slot anymore.
This change fixes the problem by only allowing the backing inventory to trigger a call to DelegateInventory->on*Change(). While we could have removed and re-added the listener instead, this way is safer since it doesn't assume that the backing inventory won't modify the given item in setItem().

This API is much more flexible than the old, allowing any arbitrary set of chunks to be ticked.
These changes also improve the performance of random chunk ticking by almost entirely eliminating the cost of chunk selection. Ticking chunks are now reevaluated when a player moves, instead of every tick.
The system also does not attempt to check the same chunks twice, leading to further improvements.
Overall, the overhead of random chunk selection is reduced anywhere from 80-96%. In practice, this can offer a 5-10% performance gain for servers with sparsely distributed players.

the code for this is borrowed from ItemEntity. I didn't feel like a base class was appropriate, and we can't (yet) declare constants in traits.
This change significantly reduces the amount of work done by event handlers. Instead of traversing all of the priorities and event parent chain multiple times, we reduce event handlers down to a simple list, which doesn't require any logic to iterate over.
Previously, calling an event with lots of parents costed more than an event which directly descended from Event.
In addition, we had to do a lot of usually useless work to check all priorities, when in practice, only NORMAL will be used in almost all cases.
This change makes it more cost effective to implement the feature suggested by #5678; however, it will still require additional changes.
closes#5670
I'm not super happy with this fix, since it can still be broken if StandardPacketBroadcaster is replaced by something else. However, fixing that problem is probably going to require internal BC breaks, which are not suitable for a patch release.
