title: Rails tolk import directory tree
body: <p>I decided to try out tolk to better manage my translations. The problem is that currently my locale strings are spread across multiple files in the /locales directory and I cannot find a way to import them all. Interesting enough</p>
  
  <pre><code>rake tolk:sync
  </code></pre>
  
  <p>managed to fetch all my base locale string, but</p>
  
  <pre><code>rake tolk:import
  </code></pre>
  
  <p>could not import the other locales except those in the **.yml files in the root dir.</p>
