1) Added the foundation for the structures section of the discovery book. Once a structure is built for the first time it will become visible in the discovery book. This will provide you with more information about the history and function of the structure.

2) The items page has also been set up and will work in a similar manner. Each time one of your villagers deposits a new item at the town center it will become visible in the discovery book with more information detailing the item.

Some things I have noticed that need to be fixed in the next update: Wall, and Home building mechanics.
