* Partial fix for bugreport:1222, if you have a pet and the pet egg is flagged as non-droppable and your inventory is full and you try to return the pet to the egg, the egg would drop; now you won't be able to return the pet to the egg.
* Fix for @item, if you use an egg id it would create it regardless of your inventory limit, dropping the item if your inventory is full; now it won't create the egg.
