Return Formula objects from `outdated_brews`

Previously, `outdated_brews` returned a list of lists---each containing three
components of a Formula object:

  - f.rack
  - f.name
  - f.version

Frequently more information is required which necessitates back-casting from
`name` to a Formula object---simpy returning formula objects removes this step.
