[gnome-shell] global: Add session-mode property

[Florian MÃllner <fmuellner src gnome org>]

commit 940ddb104c1bb6c79ab6b830735366f3d5650ba2
Author: Florian MÃllner <fmuellner gnome org>
Date:   Wed May 16 23:11:57 2012 +0200

    global: Add session-mode property
    
    Add a session-mode property on ShellGlobal which corresponds to the
    new --mode switch. Make the existing ShellGlobal:session-type property
    readonly and base it on ShellGlobal:session-mode to avoid conflicts.
