Facebook social login authentication events etc...

Facebook-social-login.js

  /* FACEBOOK EVENTS BEST PRACTICES
  ===========================
  1. For most cases, you will want to subscribe to auth.authResponseChange rather than auth.statusChange. 
  The response is returned as a javascript array, not encoded as JSON.

  2. Note that for some cases, the value of response is unkeyed, but when more than one variable is returned, it contains the appropriate keys.

  3. You can subscribe multiple callbacks to one event using different function names.
