Auto Manufacturing requests

Clinets that have items set up as manufactured items currently have 2 options: 1) Monitor items and request the warehouse to manufacture more (via email) 2) Have the warehouse manage stock, warehouse is notified that more is needed on their internal screen when an item hits 0 There should be a way when the customer assigns a minimum number to the synset that is contoling the items in that set for the warehouse to see more needs to be built when inventory hits that number. i.e a client wants us to always have 100 of an item in stock at all times, so they set up the min to be 100. When we ship unit 101 and inventory hits 100 that item should appear on the production screens as an item that is in need to manufacturing.
