Title: Extend the Facebook object so that it remembers the last access token.

This commit introduces a new class (FacebookClient) which inherits
from the Facebook object so that it automatically remembers the
session token when users complete the sign-in process.

It follows the sample code available from:
https://developers.facebook.com/docs/mobile/android/build/#token

I am available to rework the code in any way you see fit.
