Batch Payments: Disregard line in csv when amount is set to 0

[pretyflaco]

For users who are reusing a template with multiple usernames for batch payments, just setting amount to zero when individual recipients in template should not get paid in current batch payment because it's easier to set amount to zero than remove a line from csv.

It would be more convenient for folks who do recurring batch payments with same template.
