[Guillaume Desmottes <gdesmott src gnome org>]

commit 94520441d0d22f6fc8361770f66c1a1ac27e011c
Author: Guillaume Desmottes <guillaume desmottes collabora co uk>

    Set chat.facebook.com:443 as fallback server
    
    Some nasty firewalls block the port 5222, Facebook servers allow connection to
    the port 443 as a fallback in this case.
