VbzCart/tables/ctg groups

About

• Purpose: Master list of groups (CTGs)
• Fields:
  • ID_Supplier: supplier to which this group applies; NULL = no fixed supplier, can be used for any of them
  • ID_Redir: TGroups.ID -- if not null, redirect all references to the current ID to use ID_Redir instead. This is used to indicate a disused TGroup (at the moment, I can't remember why it was better to do this than to just edit the existing TGroup, but I'm sure there was a reason).
