Display percentages and amounts graphically

[vthorsteinsson]

Display percentages as a bar graph (or pie?) and amounts relative to a set of standard yardsticks, such as the price of a liter of milk, the price of a 3-course meal at a restaurant, average monthly wage, the price of a common medium size car, the price of a 2-bedroom apartment, a well-known item in the fiscal budget, the GDP of Iceland, the GDP of the Nordic countries, the GDP of Europe, and the GDP of the world.

Partially implemented. Percentages are now shown as small bar graphs in the token pop-up.
