* Include .god file in gem.
* Sanitized the sane? methods.
* Removed CommonConfiguration and CommandBuilder, merged that into the
  classes again.
* Fix CONFIG_FILE_ATTRIBUTES of Sidekiq instances not being available
  in the configure block as global (common) config options (e.g.
  requirefile).
* Removed unused :daemonize value from SidekiqConfig.CONFIG...
* Removed unused code from SidekiqRunner (`settings`).
