Having trouble setting a "default_locale" for i18n

#1

When I run my build script it executes the following command:

      activate :i18n, :mount_at_root => false```

The default language is `en` but it want the default language to be `es`. The only way I can achieve this so far is if I change `mount_as_root = es`, however, I want all the locale files belonging to `es` to remain inside `/es` and not on the root folder.

My question is, how/where do I enable the `default_locale = es` setting for i18n.
Is that feature not supported by Middleman?

Sounds like this is what you are trying to achieve: https://github.com/middleman/middleman/issues/1968.
