Fix broken members list build in Order::InvoiceCollection

I accidentally committed a class with essential code commented out.
Add Order#order_status and Order::Status
Add Order#total_value and Order::Value
Add Order#delivery and Order::DeliveryDetails
Add contact detail resources and integrate with Order

- Add Order::PartyDetails
- Add Order::Contact
- Add Order#parties
Make regexes more idiomatic and readable

- Use === when boolean return value is wanted
- Store regex in a constant
Add missing Order resources
Remove jruby support pending later investigation

Getting this error message. It appears to have something to do with DateTime or Date.

Nacre::Order.get should make a request to the correct endpoint
