VbzCart/tables/var global

About

 * Status: not currently being used, but is probably needed for proper stats display in controlbar
 * Purpose: any simple data which needs to be both persistent and easily updateable by the code
 * currently needed for tracking the current order number
 * later, may be used for storing calculated statistics for the sidebar
 * History:
 * 2009-09-27 renamed from "stats" to "var_global" to reflect new purpose
 * Name length increased from 32 to 255 to make it easier to indicate hierarchy, if needed
 * Added When* fields, mainly as a sort of debug/reality check
