List of languages in a config file instead iso-codes

Merged Daniel Garcia Moreno requested to merge language-list into master

The iso codes has the list of languages codes and the list of country codes, but there's no a list of these two mixed.

To have a custom list with language codes with region we can provide a custom list, like we provide the plural forms.

In the future this will help us to translate language names too. Right now we've a list of languages in plain english.
