[gnome-control-center/randr-hotplug: 5/5] Use the timestamp of the Apply button to change the RANDR configuration

[Federico Mena Quintero <federico src gnome org>]

commit 74e06ac80e3c34b416ca0a72615dfa11398b8d33
Author: Federico Mena Quintero <federico novell com>
Date:   Sat May 30 20:47:42 2009 -0500

    Use the timestamp of the Apply button to change the RANDR configuration
    
    There is no timestamp available when the dialog returns from gtk_dialog_run().
    So, we save the timestamp at the time the Apply button is clicked.
