title: Titanium - Facebook permissions error when asking read and write permissions
body: <p>I've read in the documentation that since Facebook sdk change read and write permissions should now be asked differently.</p>
  
  <p>If not, the Facebook SDK throws the following error:</p>
  
  <pre><code>Publish or manage permissions are not permitted to be requested with read permissions.
  </code></pre>
  
  <p>In my app what I'm doing is in login setting the <code>permissions</code> property. And I want the user to know up front what permissions he is agreeing to when he registers.</p>
  
  <p>So my question is what is the correct way to handle this? I searched the error and saw answers that are relevant to native code. What is the "correct" way to work with Titanium to ask Facebook permissions? up front just ask read permissions and then bother the user again later to give write permissions?</p>
