Title: Restore `config.assets.manifest` option

Restore `config.assets.manifest` option, which was removed in Rails 4.0.0 (see https://github.com/rails/rails/pull/7702.) This change does not affect existing behavior if the option is not set.

There is a long discussion of the reason for this in https://github.com/rails/sprockets-rails/issues/107.
