When editing a book, it now gets locked after the first save, not when the book is first opened.
Allow only the admin and the user who last edited an item to reopen the item after it's completed but before it's exported.
Added volume to the title of the currently-selected book.
Reworked the help examples page with new images and content.
Removed the Create New and Current Item menues from non-admins.
