Improve how Risk is displayed in results

[jdorn]

TODO:

• Allow user to select which variation they are thinking of choosing and display risk just for that choice
• Set risk thresholds and highlight red/yellow/green
• Intelligently choose the initial selected variation based on which one is least risky
• If a different variation is selected for an experiment, persist in localStorage
• Update the documentation (screenshot of results and explain how to change variations)
