Carlos Antonio da Silva 47b4d13c8d Ensure I18n format values always have precedence over defaults
Always merge I18n format values, namespaced or not, over the default
ones, to ensure I18n format defaults will have precedence over our
namespaced values.

Precedence should happen like this:

    default :format
    default :namespace :format
    i18n    :format
    i18n    :namespace :format

Because we cannot allow our namespaced default to override a I18n
:format config - ie precision in I18n :format should always have higher
precedence than our default precision for a particular :namespace.

Also simplify default format options logic.
