Order detail JSON should contain product details

[hannahhall]

Update the Order detail JSON object should contain all nested Product information.

For example:

{
   OrderId: 21,
   CustomerId: 16,
   PaymentTypeId: 83,
   Products: [
      {
         ProductId: 156,
         Name: "Kite",
         Price: 14.25
         Quantity: 1
      },
      {
         ProductId: 212,
         Name: "Roller blades",
         Price: 88.99
         Quantity: 1
      }
   ]
}
