Add translation functionality for text of reminder mails
When users choose to receive a reminder by email. They receive an e-mail with a standardized text. This text is currently in English only. The standard text in the body of the e-mail can be found in the repository under /reminders/templates/emails/reminder.
People should receive the email reminder in the language of their choice. Ideally the language of the reminder mail should be the same as the language in which the corresponding request was generated initially. This would require two additions:
- An option to easily create different language versions of the reminder mail.
- The language of the reminder mail should sync with the language of the request generated for which the reminder is set.
