[Dextrose] [PATCH v4 sugar] Shutdown (and Logout) menuitems should activate

[Anurag Chowdhury]

We changed the cursor in home window to a busy cursor when the shutdown menu
is activated and used glib.idle_add( ) to call the shut funtion when pygtk is
idle to shutdown or logout the sugar session properly , hence letting the user
know  the validity of the shutdown process going on in the backend.
