[mutter] window: Add "skip-taskbar" property

[Florian Müllner <fmuellner src gnome org>]

commit 52c24c5c7164d1389ec7fc0b30bd8480701e8e6b
Author: Florian Müllner <fmuellner gnome org>
Date:   Thu Jan 30 16:40:59 2014 +0100

    window: Add "skip-taskbar" property
    
    We currently only have a method to query the skip-taskbar hint.
    Add a corresponding property to allow listening for change
    notifications.
