Currency Formatting

Using v2 merge data with tag templates, we need a field with a formatted currency value.

For example, using project_payments.schedule.amount_due , I can get the price into the document and, while using currency.unit we can get the appropriate symbol entered (e.g. $), however, the amount due doesn't format correctly. It simply inserts a number (e.g. 15002.2) instead of properly formatting it for currency ($15,002.20)
