IPayPalTransaction missing fields

[nodehack]

I'm not sure of the comprehensive list but from paypals documentation there are a lot of missing fields in the IPayPalTransaction type.

// Set up a payment
payment: function(data, actions) {
  return actions.payment.create({
    transactions: [{
      amount: {
        total: '30.11',
        currency: 'USD',
        details: {
          subtotal: '30.00',
          tax: '0.07',
          shipping: '0.03',
          handling_fee: '1.00',
          shipping_discount: '-1.00',
          insurance: '0.01'
        }
      },
      description: 'The payment transaction description.',
      custom: '90048630024435',
      //invoice_number: '12345', Insert a unique invoice number
      payment_options: {
        allowed_payment_method: 'INSTANT_FUNDING_SOURCE'
      },
      soft_descriptor: 'ECHI5786786',
      item_list: {
        items: [
        {
          name: 'hat',
          description: 'Brown hat.',
          quantity: '5',
          price: '3',
          tax: '0.01',
          sku: '1',
          currency: 'USD'
        },
        {
          name: 'handbag',
          description: 'Black handbag.',
          quantity: '1',
          price: '15',
          tax: '0.02',
          sku: 'product34',
          currency: 'USD'
        }],
        shipping_address: {
          recipient_name: 'Brian Robinson',
          line1: '4th Floor',
          line2: 'Unit #34',
          city: 'San Jose',
          country_code: 'US',
          postal_code: '95131',
          phone: '011862212345678',
          state: 'CA'
        }
      }
    }],
    note_to_payer: 'Contact us for any questions on your order.'
  });
},

These fields should be exposed on the IPayPalTransaction type.

I'll take a closer look at these.. I wish there was better documentation on these properties by PayPal as I don't even remember seeing this example when I was initially making this library.

I added more properties (3.2.0 release). Let me know if something missing.
