feature request: internationalization

[songsammy]

I see this as a wonderful project. If you can do i18n (Internationalization), then I can do l10n (localization).
Internationalizing (i18n) a Django app involves preparing it to support multiple languages and adapting it to different locales. Django provides a robust framework for i18n.

A PR which replaces user-facing strings in the form of "string" to _("string") would be most welcome.
