Added support for incoming transactions that are not only in stellars. Now transactions are agregated instead of being added directly. Also unsuccessful transactions are not added to the transactions array (engine_result != 0).
Moved dust to stellar conversion to the last step in the balance aggregation to reduce rounding errors.
Removed bug introduced by calculating stellars last.
Now the account balance and info is updated via the meta.AffectedNodes in the transaction message.
Now transaction values are filtered by toFinancial filter. Also the addresses in incomingTransactions are now links.
