Internationalization support for the nunjucks templates

[fynnlyte]

• use header information from the requests to determine the current language
• use some configurable folder structure or whatever nunjucks offers to send out a localized template based on the language header

It is great idea :) It should be able to send a header to local.confirmEmailRedirectURL too or using parameter to callback ?success=true&lang=en or "error=...lang=en" for example to be able to display correct localized html page to the user.. The language can be also set on registration as field and saved in sl-users, but if someone wants to change the language on that user, that should be than possible by another api call for example. Or better approach can be the custom header for every API call.. And of course some change to nunjucks folder structure templates/[lang]/email with some default lang (as en) fe. I vote for this enhancement :) Thank you.

Yeah, that makes sense.

Or maybe just use the Accept-Language Header. I don't think I want to add setting a language via sl-users in couch-auth.
