v1.4.0

Changed

• Books: Now use a folder-based structure with separate chapter files instead of a single document.
• Legacy books are marked and can be migrated to the new format. Your old file will still be available with a .bak extension.
• Chapters are automatically combined into manuscript.md when you compile. chapters.md also gets created automatically allowing you to reorder chapters.
• The manuscript is read-only (in Prosaic) and regenerated on every chapter close or save (including auto-saves).
