[TYPO3-mvc] extbase - translate label for other language

[Viktor Livakivskyi]

Hi, Krystian.

Ah, I see the problme now. We've faced it one time in former project and also found no easy way to do this.
The solution was dirty: store current language, set $GLOBALS['TSFE']->config['config']['language'] to desired language, re-init LocalizationUtility, render template with language labels, re-store original language and re-init LocalizationUtility once again.
