More user transaction retrieval API cleanup

More user transaction retrieval API cleanup

Use consistent xact fleshing mechanism for circulations both for
less/cleaner code and to consistently take advantage of CSToreEditor for
authoritative support.

Added .flesh option to transaction history api calls, consistent with
non-history version.

Added a have_payments history call so we can limit retrieval to xacts
that had at least 1 payment

When making sub-req calls to payment API calls, call .authoritative as
appropriate
