Bug Fixes and Minor Adjustments

• Added a way to mark a warehouse location as containing items that are pulled on demand in Fulfillment Pro (when the customer arrives).
• Changed order and invoice general assembly forms to not ask for confirmation when deleting detail lines.
• Fixed: Posting an invoice with a general assembly was not updating the cost on the invoice detail line. It now will update it to the actual cost used in the assembly detail. 
• Fixed: the discount button on orders/invoices was ignoring the completed/posted status.
• P10: Fixed: opening an inventory item in P10 and viewing the assembly detail was setting all components to the master product ID.
