No more `antialiasing` key

[cassidyjames]

On OS 7:

No such key “antialiasing” in schema “org.gnome.settings-daemon.plugins.xsettings:Pantheon” as specified in override file “/usr/share/glib-2.0/schemas/default-settings.gschema.override”; ignoring override for this key.

It seems to have been replaced by font-antialiasing option in org.gnome.desktop.interface.
