Update localized files

I added the following:
* configured cues file too 
* set license after "resources" tag to keep it while retrieving data from Transifex
* use proper spaces (2 spaces instead of tabulation) - this seems to be the standard, or at least the one used by Transifex. Moreover, every empty lines in the .xml files were removed automatically by Transifex, does it matter?

Jonas, if you want to admin the Transifex project too, please send me your Transifex account ;)
