Update histroy for new outputs, spinner for active

A spinner is now displayed when  a job is actively executing
- Spinner has slightly incorrect sizing
- Only one spinner is displayed regardless of output count

History tracking change makes me very unhappy. I want to clean this up
to correctly leverage vue reactivity in the future, but required
functionality comes first
