[TYPO3-mvc] Localize objects and templates in CLI mode

[michal_cygankiewicz at interia.pl]

I'm using the TYPO3\CMS\Fluid\View\StandaloneView in a CommandController
 to send emails via scheduler job which runs by CLI. This works well in the standard language, but i've no 
idea how i can tell the View/CommandController to use other language? In
 e-mail templates I am assigning extbase objects which should also be 
localized (also with childs relations).
