global.php was added, as it should have been in the previous revision.
This revision includes the following changes:

 - [1] The sell-books/index.php page had its old content removed and has been replaced with the new UI, with much many of its form input elements already tied to a database.
 - [2] The root configuration file has been rewritten to conform to the latest plugin standards for class instantiation and constant definitions.
 - [3] global.php now includes jQuery, the main plugin stylesheet, and bootstrap, which replaces Delfini UI.
 - [4] main.css, bootleg.css, and sell.css have been added, most of which controls the UI for the sell-books/index.php page
 - [5] library.jpg and step-circle.png have been added as images which are used on sell-books/index.php page
 - [6] New Essentials and Interception_Manager classes have been added to replace the outdated standards of the FFI_BE_Essentials and FFI_BE_Interception_Manager classes
