TODO: Facebook, ask customer to input email manually

[mpalasis]

Under some specific conditions facebook will not return the email amongst the other data in the final redirect to /socialconnect/facebook/connect/

TODO: Apply modifications where needed to ask the customer to enter email address manually if it's missing from the redirect.

Priority low, because it will work the first time as intended, but if the user (see: me) plays with it a bit and adds/removes/disconnects etc, then fb will stop giving the email. Unknown if this will also occur under other scenarios. Tip: FB will not give the email if the app is already accepted/authorized in the FB account, but will silently succeed without asknig for reauthorization of the data the app can see.
Alternate fix: have the module ask for the specific email data on the fly ?
