JSON spec missing deepLinkURL

[tom-a-horrocks]

The get_transactions and get_transactions/{id} endpoints include a deepLinkURL through the response object: data.attributes.deepLinkURL. This isn't present in the JSON spec (should be in attributes around here).

The other properties listed in the API changelog (performingCustomer, transactionType , and note) are all present.

EDIT
I see there's already a merge requrest implementing this: #150.
