button which takes me to the most recent green->red state transition

[zooko]

I see that a build slave is red. I would like to click a button and zoom to the most recent time that it transitioned from green to red.

Currently I do this manually by scanning through the page, clicking "next page" and scanning through that page, etc., until I see the transition.

This is often easier to see in the grid view than in the waterfall, but it's not a bad use-case anyway.

This will be easier when we have build status in the db.
