[gnome-shell] Replace 'enable-app-monitoring' setting

[Florian Müllner <fmuellner src gnome org>]

commit 731e8bfe2b7b628171e56c6168a07e1138247758
Author: Florian Müllner <fmuellner gnome org>
Date:   Sat Mar 2 00:56:18 2013 +0100

    Replace 'enable-app-monitoring' setting
    
    The org.gnome.desktop.privacy schema gained a 'remember-app-usage'
    key, use that instead of our own preference.
