batch list does not display accurate currency

Problem:

The batch listing pages (open, closed, etc) display a total amount column with a currency symbol prepended to the amount. However the currency value only ever displays the system default. Even if all the transactions in the batch use a different currency, it will display the system default.

Solution:

For each row, use the appropriate currency symbol for the total amount based on the table that the total amount field comes from, i.e. either financial_trxn or financial_item.
