[gnome-online-accounts/wip/modules: 4/8] facebook: Split it into a loadable module



commit 5b54fdeaf7772e35fcdc6506ea13d4baeb28c2b3
Author: Debarshi Ray <debarshir gnome org>
Date:   Tue Apr 29 15:59:56 2014 +0200

    facebook: Split it into a loadable module
    
    As a side effect, the documentation has been removed. There is no point
    in scanning yet another shared library when there are no symbols that
    need documenting.
    
    Fixes: https://bugzilla.gnome.org/729173
