Merge pull request #13 from klaoha06/set_time_out

There are timeout session on both side, client and server. It is checked by the access_token received from FB. It is stored in the cookie on the client side. I setup Ajax in _navbar.jsx so that every request is send along with this access_token everytime to our api. If the access_token is wrong or is timed-out then the request is rejected.
