Facebook are deprecating XMPP [1].

  On April 30, 2014, we announced the deprecation of the XMPP Chat API as part of the release of Platform API v2.0. The service and API this document covers will no longer be available after April 30, 2015.

  Once version 1.0 is deprecated on April 30, 2015, chat.facebook.com and the xmpp_login permission will no longer be available.

  We recommend developers who have integrated with the XMPP Chat API deprecate this functionality from their apps before April 30, 2015 to avoid broken experiences.
