title: how to skip the "install page" for a facebook app?
body: <p>thank you for your time first.
  I have a very simple question here,but I can't figure it out for an entire day.
  I built an facebook app which just post a message to wall,the problem is it requires user install the app first then request permission,that means 2 clicks,I don't like.</p>
  
  <p>I saw somebody merged the 2 steps into 1,how did he get it?
