Challenge http://www.freecodecamp.com/challenges/bonfire-roman-numeral-converter has an issue. Please describe how to reproduce it, and include links to screenshots if possible.

I've noticed some other bonfires provide a wikipedia (or external) link with useful information on solving the challenge (i.e. Bonfire - Map the Debris). I feel this bonfire could benefit by adding the wikipedia link to roman numerals: https://en.wikipedia.org/wiki/Roman_numerals
