* Added a checkbox in the plugin settings using which website admin can hide the supplier name from the Orders page on the frontend
* Added a feature using which only that shipment will be marked as complete for which the supplier clicked on the corresponding link from the notification email (and not the complete order).
* After this release, for the already existing orders in all the websites, the corresponding "Mark as complete" links will no more work from notification emails (because earlier they were marking the order itself as complete and this was a bug).
* For all the new orders that will be placed, the "Mark as complete" link will work as desired.
* After this release, the order will be marked as complete only if all the suppliers asociated with the order, has marked their shipment as complete.

* Fixed packing slip not showing correct order ID
