title: Permission migration from publish_stream to publish_action
body: <p>I am wondering if you have a users permission to publish_stream and you want to publish_action from now on does publish_stream cover both or do we need to re-request the users permission?</p>
  
  <p>If so whats the easiest way of detecting wether they have this permission granted etc.</p>
  
  <p>User journey suggestions welcome.</p>
  
  <p>The login system I have in place is users can use with facebook or their account credentials.</p>
  
  <p>But some users sign up without facebook and then connect later. I don't create the session every time they login as I only need the publish_stream permission which works without needing a live user session with facebook to post when the user does specific actions. There is one column in the table which specifies wether the user is connected or not.</p>
  
  <p>Suggestions welcome.</p>
  
  <p>Thanks!</p>
