Multilanguage support

[jedie]

I start a 'proof-of-concept' for multilanguage support.

As i described in #179 , the idea is:

1. create a form in default language (settings.LANGUAGE_CODE)
2. create a translation for all lables in one of the languages from (settings.LANGUAGES)
3. render the form will used the translation, if available or fallback to default language

This worked yet for me. But it needs some love and tests. I'm waiting for feedback how this pull request can be accepted and merged ;)

Some notes:

I expand the example project:

• activate languages
• set default language (settings.LANGUAGE_CODE) to en
• fill settings.LANGUAGES with en,de and fr

I add the "translation" links into Form change view (/en/admin/forms/form/) here:

---

---

The Admin translation view looks like this (in this case in german):

---

---

Notes on this view:

• you see only fields that are used in the origin form
• the django translation change to the destination language
• The help_text contains the origin value
• Every field is optional

And here i send the form in English:

---

---

and now the same in German:

---

---

And the entries:

Maybe it makes sense to save the language used for send the form, too?!?

This is already implemented in https://github.com/stephenmcd/mezzanine/tree/master/mezzanine/forms - the implementation here should mimic that.
