Set source i18n language

[Olegt0rr]

Prerequisites

Code example

text = _("Hello")  # source lang is 'EN'

Project tree

...
locales
├── bot.pot
├── ru
│   └── LC_MESSAGES
│       └── bot.po
├── uk
│   └── LC_MESSAGES
│       └── bot.po

Middleware setup

i18n = I18nMiddleware(I18N_DOMAIN, LOCALES_DIR, default="ru", source="en")  

Problem

For this case we should create empty 'en' translation.
If we ignore it, i18n returns default language, cause locale is not in locales.

Suggestion

Add home or source or similar named param to set a source language.
If user.language is "en", i18n shouldn't translate anything, just return an original text.
