VbzCart/procs/Upd SupplierIttyps

About

• Input: cat_supp, _titles, _title_ittyps, cat_ittyps
• Output: _supplier_ittyps (delete/insert)
• Notes: Later we might refine this into a way to view unavailable suppliers as well... but that's very low priority, and it might be better to have a separate table for it anyway (keep "active" operations fast).
• History:
  • 2010-11-10
    • Added DROP PROCEDURE for easier maintenance.
    • Created in database (procs were not ported from L48 to Rizzo) (why did this one work without any DELIMITER commands?).
  • 2011-02-02 Added WHERE tc.cntForSale>0 so it wouldn't count titles with nothing for sale (duh).
