[TYPO3-mvc] extbase way of accessing folder based file collection

[Domi]

Hi again,

I really don't know where the different is. I use now in my controller 
almost the same code than in media_gallery.

https://github.com/dohomi/flux_galleria/blob/master/Classes/Controller/GalleriaController.php

In function getFileCollectionItems() there you find the code. The else 
condition works, but I never reached the folder name till now.

Cheers,
Dominic
