Allow to choose a language (visitor and/or admin)
Is your feature request related to a problem? Please describe
It would be nice for the visitors to be able to choose a language, that could be different from the default one set on their browser.
Also, it would be nice for the admins to be able to set a default language for the entire instance.
Describe the solution you'd like
- allow the admin to set a default language (if there is not, use the visitor's browser's default language)
- add a button or select to the footer (next to Home/Credits/Map…, or somewhere else?) for the user to be able to switch language
Additional context
I run an instance dedicated to minority languages in Brittany, France. Since it's mainly visited by people understanding the Breton language, I'd like to show that language first.
It often happens that minority languages are not set as defaults in browsers, so when an instance is dedicated to one of them, it would be nice to show that it is available in that minority language.
