 `get_language_info` tag returns english name and local name of language:

 {{{
 language.local_name == česky
 language.name == Czech
 }}}

 Neither depends on active language, but sometimes there's need for
 translated language name, ex.  tchèque (in French). The only way how to do
 it right now is to take the english name and run it through `gettext`
 since Django already has all languages translated.

 This would be very handy filter tag:

 {{{
 @register.filter
 def language_translated(code):
     """
     Return language name translated into active language
     """

     name = translation.get_language_info(code)['name'].capitalize()
     return translation.gettext(name)
 }}}

 ----

 Maybe we could also extend dictionary returned by the `get_language_info`
 tag with `name_translated` to keep API consistent. All keys from
 `get_language_info` have matching filter variants (`language_name`,
 `language_name_local` and `language_bidi`).
