Upgrade StorageBetter input for book sections
When you have an edited volume and want to add a book section, you have to add an author-field manually and the page-numbers are somewhere in the middle of the column.
Better solution:
1. The field for the author of the book-section should e added automatically.
2. The relevant fields of the book-section (author, title, pages) should be on top.
3. The fields of the edited volume should be greyed out, so that you can't accidentally change them. Editing fields of the edited volume should be done in the parent-book, so that these edits are correct in all book-sections.
