[rygel] ui: Treeview to handle 'folders' option

[Zeeshan Ali Khattak <zeeshanak src gnome org>]

commit 1a59a45a5808a2928234868f305c182b429a7908
Author: Zeeshan Ali (Khattak) <zeeshanak gnome org>
Date:   Tue Jun 2 17:32:02 2009 +0300

    ui: Treeview to handle 'folders' option
    
    Instead of providing a text area to put the paths, provide a treeview
    and buttons to interact with it. For now only clear button works.
