gd2 for new PHP-GTK2 release

Hi,

The windows binary of the previous beta release included the gd2 library.

But the gd2 was not in the latest official PHP-GTK2 release.

The ability to use gd2 libraries right inside PHP-GTK2 application is a useful one.

Would be great if this could be added to the latest release.

Thanks and Regards,
