VbzCart/tables/ref country

About

 * Fields:
 * ShipZone: a text code indicating the "shipping zone", which is a shorthand way of estimating shipping cost multipliers for non-domestic delivery. The values are calculated in the clsShipZone class which is currently in shop.php and should eventually be broken out into a separate module for easier customization VBZ uses these codes:
 * US: United States (domestic)
 * CA: Canada (2x domestic costs) - would probably work for Mexico too, but we've never received any orders to be sent there...
 * NULL (default): everywhere else (4x domestic costs)
 * History:
 * 2012-01-11 created, along with, so that ultimately we can rigorously get rid of the country being shown in the address when it's the same as the shipping origin (in vbz's case, "United States").
