title: Strange folder structure when adding language
body: <p>My app is Base language English. 
  I have added German, and Xcode generated automatically a folder structure that doesn't correspond to what the documentation says. (cf screenshots from Xcode and Finder).</p>
  
  <p>When I run genstrings, it only generates stuff for the english strings (the german remains empty).
  I manually copy then the English strings into the German strings, but Export ignores the German strings in the cliff file</p>
  
  <p>What am I missing?</p>
