@hackage acme-everything2015.5.4.1

This package requires the entirety of Hackage to be built. The joke started when a colleague liked the leftToMaybe :: Either a b -> Maybe a function from either, which has a *huge* footprint compared to the utility it provides. This got us thinking about seemingly small packages that have lots of hidden transitive dependencies, e.g. "only" base, lens and yesod. And that's where `acme-everything` was born, which (transitively) depends on the entirety of Hackage.
