* Working towards notifying the client if the inventory service has failed, rather than simply returning 0 items.

* This is very early support which would only be triggered in a rather unlikely case (if the user server correctly received an inventory skeleton, but later on failed to return the whole inventory in a timely manner.  Also, this only applies to the 1.19.1.4 client onwards
* Code cleanup and support for other failure cases (failure of inventory caching on region crossing, failure to actually add a folder/item, etc, should follow.
