As discussed, I've dropped the optional last argument `locale` of the static functions (eg. Globalize.formatDate( value, format, locale )), since user has now plenty of alternatives to do so: statically via `Globalize.locale( locale )` or via instances, eg. `[new] Globalize( locale )`.

This allowed to reduce the boiler plate code by using your `this.cldr` approach on both methods (static or instance).
