Title: Added author search and missing author validations.

Summary of changes:
•	Added Author validations per slide 23: presence of nationality, biography, image_url and minimum length of biography.
•	Removed SQL injection on search and added author search functionality.
•	Modified new book page so that there is no error when a book fails when it is created (this implementation isn’t perfect, but it keeps rails from throwing up any error pages).
