displayNumber added to orders API

The Order object in the orders API has been updated with a displayNumber value that provides a number for each order in a single day. Typically, the displayNumber value starts with 1 for the first order of the day and increments by 1 for each additional order placed that same day. displayNumber restarts each day. This pattern, however, is not guaranteed and you should not rely on it when programming critical functions for your integration.

While the displayNumber typically contains numeric values, it is of type string.
