[baobab/import-export: 5/9] Add timestamp of last completed scan

[Stefano Facchini <sfacchini src gnome org>]

commit 17dfdb9a69e5eabe7d4e4b503e4f39d94830fad3
Author: Stefano Facchini <stefano facchini gmail com>
Date:   Sun Sep 9 14:50:45 2012 +0200

    Add timestamp of last completed scan
    
    Show in the toolbar the timestamp of last completed scan.
    The format of the time indication is currently quite pedantic
    and could be improved.
