Update v1.13.0

# New Puzzle Objects and Item Images

You can now create mergeable puzzle objects that require specific items in a specific order.

Objects can:

- Display required items.

- Accept items one by one.

- Give a reward after completion.

- Be removed after completion or reused.

- Show required items above the object.

- Consume only the correct item in the sequence.

Unique item descriptions can now display item images directly inside the inventory.

This makes books, clues, and puzzle instructions easier to understand.
