[baobab/wip/vala] Start to implement "Scan remote dir"

[Paolo Borelli <pborelli src gnome org>]

commit b8e2465e11a1502e61ec4671d65bf9c3d5ce4217
Author: Paolo Borelli <pborelli gnome org>
Date:   Sat Feb 4 00:09:56 2012 +0100

    Start to implement "Scan remote dir"
    
    Instead of reimplementing it, spawn nautilus-connect-server and grab the
    output uri. The actual scanning does not work yet.
