Translation

I have added support for Kdyby\Translator. This change does not affect users which used default Grido translations.

Users of Kdyby\Translator just need to add one translation file for each language with name <code>Grido.en_EN.neon</code> where <code>en_EN</code> is desired locale. For more informations look at: <code>o5/grido/Grido/Translations/en.php</code> or any other locale.
