Subject: [PATCH] Use id instead of link to identify Facebook users
The link property of Facebook Oauth profiles no longer has a consistent
value across logins and will be completly removed in future versions of
Facebook's Graph API.
We generate a link in the old format from the id for backwards
compatibility.
