Added the database schema file.

To create the actual database, run the following command:

sqlite3 creepypasta_files.db < creepypasta-files.sql

This will provide the necessary schema for creepypasta files. To add
stories, simply use standard insert commands. To reference images, add
the image to the Raw folder and use a standard HTML tag. For example:

<img src='hello.png' />
