* Add label on each benefit (yet to be internationalized)
* Add unit on each benefit (yet to be locale-sensitive)
* Add number format string on each benefit
* Simplify template to use a loop

* extrapolated benefits are larger than non-extrapolated benefits

Also, simplify extrapolation calculation and reformat its code a bit
