- Moved the TransactionNotFound exception to a more appropriate place. - Changed the serialization for AccountingExceptions - Override the Exception.__init__ method in AccountingException - Added __eq__ methods to accounting.models.* - Catch the TransactionNotFound exception in transaction_get and return a 404 instead. This could be improved, perhaps in the jsonify_exceptions decorator so that all endpoints that raise a TransactionNotFound exception automatically return a 404.
