addBook added - contains the start of an SQL script to add information about a new book to the database.
catalogue fixed to use jQuery style elements, although I'm having some trouble with the dropdown menus. We should look at this on Friday and choose the layout you like best.
Modified inventory.php to work with addBook.php
Only thing I did in App_Index.php was modify it to use my local copy of jquery.min.js when working offline- that's now commented out.
