Renamed to winners. Winners gets controller setup.

Rewrote everything that happened in history to better take advantage of
monogdb instead of doing everything in js.

Our endpoints become:
 - /winners - getAll w/ includeWines and sort query params.
 - /winners/latest - latest winners grouped w/ includeWines query
 params.
 - /winners/by-date - all winners grouped by date w/ includeWines and
 sort.
 - /winners/by-date/:date - get winners per epoch or string date.
 - /winners/by-name/:name - get winner by name parameter w/ sort for
 wins direction.
