## Description
Allows some fields to be collapsed in the version diff view. The fields
that can be collapsed are the ones which can also be collapsed in the
edit view, or that have visual grouping:
- `collapsible`
- `group`
- `array` (and their rows)
- `blocks` (and their rows)
- `tabs`
It also
- Fixes incorrect indentation of some fields
- Fixes the rendering of localized tabs in the diff view
- Fixes locale labels for the group field
- Adds a field change count to each collapsible diff (could imagine this
being used in other places)
- Brings the indentation gutter back to help visualize multiple nesting
levels
## Future improvements
- Persist collapsed state across page reloads (sessionStorage vs
preferences)
