Stacked currency value charts

Today we have added a couple of new chart features. We've added two new chart types, including a Converted Portfolio History chart. This chart displays the historical value of each of your portfolio currencies, converted into a target currency:

You can add this chart to your portfolio by either resetting your portfolio charts to their defaults, or by adding the chart manually through Add Chart > Value.

We have also added the ability for line charts to be stacked, either in terms of absolute value, or as 100% stacked charts:

Thank you to John for the feature suggestion!
