Titlepages used to get created in the submitted_images dir, but this caused issues if multiple files are submitted at once. Changing this so that titlepages are created in each book's done/isbn/images dir. Tested on staging, and tested dropping 4 books at once, and all seem to have converted correctly.
Fixes #26
@mattretzer can you review and merge if it looks ok?
