    lib: Add note about default adapter
    
    The selection of the default adapter depends on the return value from
    g_dbus_object_manager_client_get_objects(), and not quite "the first
    adapter plugged in" (on cold starts at least) as mentioned in
    68852faa5a957d14480e72e8e63bc8e1196d19cf.
    
    Reproduced on Fedora 20.
