title: Google oauth via devise and omniauth/oauth continually requesting access
body: <p>I can use devise with omniauth (oauth NOT openid) and a devise.rb config like this:</p>
  
  <pre><code>config.omniauth :google, KEY, SECRET
  </code></pre>
  
  <p>and it correctly does the redirection to google to ask permission (and returns)...</p>
  
  <p>but unfortunately it always does that.  It should (I believe) know that I just authorized permissions to use google and should skip that redirection to google after the first time.  Any suggestions on how to get this working?</p>
  
  <p>The permissioning I'm talking about is:  "The site blah.com is requesting access to your Google Account for the product(s) listed below".   I don't want this page to always reappear. </p>
