Show unstable builds as yellow.

This is based on pull requests 2 & 7.

Unstable builds both with and without failing tests appear as yellow.

One issue with the current implementation is that builds that are unstable
due to being marked that way (with no failing tests) aren't enlarged as
broken jobs are.
