* `i18n.callbacks` In the development environment, sets up a `to_prepare` callback which will call `I18n.reload!` if any of the locales have changed since the last request. In production mode this callback will only run on the first request.
* `active_support.initialize_whiny_nils` Requires `active_support/whiny_nil` if `config.whiny_nils` is true. This file will output errors such as:
```
Called id for nil, which would mistakenly be 4 - if you really wanted the id of nil, use object_id

* `active_support.deprecation_behavior` Sets up deprecation reporting for environments, defaulting to `:log` for development, `:notify` for production and `:stderr` for test.

Can be set to an array of values.
* `active_support.initialize_time_zone` Sets the default time zone for the application based on the `config.time_zone` setting, which defaults to "UTC".
