load lib in production env

[EstevanBR]

the guide says to put:
config.autoload_paths << Rails.root.join('lib')
in config/application.rb

this is sufficient in development environment, but the following needs to be added as well:
config.eager_load_paths << Rails.root.join('lib')
other wise files in lib are not loaded when booting the app in production
