Updated the Archive-class to take controller input

Also fixed a bug with the selection and added a delay to the cursor
movement to aid the controller input method.
Begun working on the BookManager

A book can now be transferred from the book manager to the player's
archive, though it still needs the turn based system to function
properly. Made further changes to the Archive class that allows it to be
used for both the player and the book manager.
