Patchs for shipping worldwild international

Now you can leave one zone blank which means that this zone contains all the countries in the world except those have been listed in other zones. For example, there are two zones currently defined, zone 1 and zone 2.

In zone 1, the countries are US and CA. Then if zone 2 is blank, all the countries in the world except US and CA will be in zone 2. It solves the problem of filling in as many as the countries you want to ship to by simply leaving it blank to reach the goal.

To use it, just replace the original file zones.php with the file you download here. To avoid any problems caused by version conflictions, some comparisons are strongly suggested before you use the version downloadable here.
