Revise display on note versions index

- Body now uses the diff builder to highlight changes
-- A generalized diff-body class was added instead of something specific
- The status changes are now verbalized instead of being shown with styles
- The position and sizes are now split up
-- Changes directly reference the previous version
- The date and user columns were combined
-- This is more in line with other indexes, plus it saves space
