[gnome-shell] a11y-status: Use GSettings to access the magnifier

[Florian Müllner <fmuellner src gnome org>]

commit 24669e3ba7195dd30922e2853333d8dea4f598a5
Author: Florian Müllner <fmuellner gnome org>
Date:   Tue Nov 30 18:32:06 2010 +0100

    a11y-status: Use GSettings to access the magnifier
    
    The magnifier should be enabled/disabled via the appropriate
    GSettings key - otherwise the setting gets out of sync with the
    actual state of the magnifier.
