We will default this option to true from now on to ensure users properly
handle their list of available locales whenever necessary. This option
was added as a security measure and thus Rails will follow it defaulting
to secure option.
Also improve the handling of I18n config options in its railtie, taking
the new enforce_available_locales option into account, by setting it as
the last one in the process. This ensures no other configuration will
trigger a deprecation warning due to that setting.
This can be turned off by setting `config.reload_classes_only_on_change` to false.
Extensions like Active Record should add their respective files like db/schema.rb and db/structure.sql to `config.watchable_files` if they want their changes to affect classes reloading.
Thanks to https://github.com/paneq/active_reload and Pastorino for the inspiration. <3
This handles the case where config.cache_classes is true and classes
are loaded before the I18n load path has had a chance to be populated.
