Fixed Credits Page

-Fixed secret ending hint on credits page. 

If you had only discovered one of the two hidden pages required for the secret ending, the hint for discovering said ending wouldn't show up on the credits page. Now it is set up that if you go for Ending 1 through the Close the Book route with only one of the two pages discovered, the hint will appear on that page. As a note, after finding both hidden pages, if you use the Close the Book route, it will no longer show the hint. That is not the secret ending. You may need to study up on your prayers again.
