Subject: [PATCH 01/28] The new facebook api requires to pass along
 profile_fields. If this is empty you will not get the email back, even if
 that is defined in the scope. An other change is that you also need to pass
 along public_profile along with email in the scope for this to work. (#37)

Subject: [PATCH 28/28]     Logging in detail

    Different people are facing different issue
    but we are not able to identify the issue
    since the error from the client (facebook)
    is not being thrown back to the user.

    This change will provide correct message from
    the client.
