Remove country and script specifications from languages

A language is only 'en', a locale is 'en_US': remove country codes from
getLanguageList so that we have only languages and not locales.

Furthermore we don't need to tell Punic which is the active locale:
Localization::changeLocale already sets the Punic default locale.
PSR-2
Reload countries if the current locale has changed
Add CountryList::getCountriesForLanguage
PSR-2
Improve country handling

- suggest a list of countries for a specific language
- allow selecting a language without a country for locales
