added service level to producers to help with ranking and sort order...

    Producer/Grower List Sort -
         if service level = 2 (local) always display 1st in the order:
            1) number items ordered (high to low)
              - Use: ProducerHub.getOrderItemCnt(producer.getPID())
            2) abc's

         else
            1) number items ordered (high to low)
              - Use: ProducerHub.getOrderItemCnt(producer.getPID())
            2) abc's

-All tested and working!  -- Kevin
