    filechooserentry: Keep an extra column for the full path
    
    This is identical to the display name when not having a path that
    changes the folder. Otherwise it will have the full path that was
    entered in the entry. Say when from your home dir, you type
    "../../usr/li", the full path for "lib" and "lib64" will be
    "../../usr/lib" and "../../usr/lib64" respectively. This value isn't
    used yet, but will be soon.
