[Juan A. Suarez Romero <jasuarez src gnome org>]

commit c6856a1fe1385b62a0846d4d7a7fa3914a18efe7
Author: Joaquim Rocha <jrocha igalia com>

    [filesystem] Get paths to show from the configuration files
    
    Gets the FS_PATH strings assigned in each of the provided
    configuration files. If no FS_PATH is set, then the old
    behavior of showing the root's contents is done.
