commit c9ce5786d8c0f8409249b3aff99c4262610c1e75
Author: Carlos Garcia Campos <carlosgc gnome org>
Date:   Sun Feb 5 14:15:20 2012 +0100

    Add Send To action to file menu
    
    It uses nautilus-sendto to allow you to send the current document by
    email, to a removable device, etc. If nautilus-sendto command is not
    present in path, the menu item is hidden.
