Read From Book Clutter Items

Makes it so you can click on the row or stack of books clutter items and use the read interaction. I only added the interaction for book rows/stacks that have 3 or more books. I'm going to make a seperate mod that adds the read book interaction to clutter items that have just 1 or 2 books. It uses the same bookshelf grab animation that's already in the game, so it'll look odd if the book clutter items are placed low or on the floor.
