VbzCart/queries/qryPkgLines qtys done

About

 * Requires:
 * Returns: "done" quantity for every line of all packages which have been checked in each order
 * In order to return a current quantity status for each item in an order, this query should be filtered for that order ID (ID_Order) and then summed in code; summing in SQL and then filtering doesn't speed things up. (There's probably a way to do this in MySQL using advanced syntax I haven't dug into yet.)
 * History:
 * 2011-05-31 created for packing slips
 * 2011-06-01 added p.Seq so code can filter for packages before the current one -- so that the results will be the same (at least in theory) even after other packages have been created
