**Rationale**: In certain cases, there might be a need to add new pages to a book. In that case, every Page: namespace page that has already been created will need to be moved to make room for the new page. It would be great to have a tool to simplify this process
**Example:** If I upload a book (File:Example.djvu (say)) with 40 pages and then want to reupload a book with a new page at the 20 position, then I will need to move Page:Example.djvu/21 to Page:Example.djvu/22, Page:Example.djvu/22 to Page:Example.djvu/23 and so on.
