* Imports a file with translations into the translation system.

* File must contain vaid JSON data with key-value pairs of strings in an array.
* Sample:
* <code json>

* - The key names will be ignored, only the order counts
* - The contents must be in the language defined by the `$lang` parameter
* - The uploaded file must be given as 'json_file' (`$_FILES['json_file']`)
* @param string $lang The language the contents are given in
