function fb_token_invalid in Drupal for Facebook 7.4

When a token is known to have expired, this function flags it no longer valid. It will no longer be a choice in admin forms.

Care must be taken before calling this. A facebook graph request could fail for other reasons (i.e. a timeout or https://developers.facebook.com/bugs/285682524881107/). Should be called only when certain that a token is not valid.
