Dynamic favicon for branch pages


Hello! The dynamic favicon on a build page is super useful when I’m working on another tab or another screen and can just peek to see when blue becomes green or red. Often, I make a succession of commits on the same branch and push them one at a time to make sure I don’t break the tests or the dev server, and it’s a bit of a chore to go to the page and click around to go to the most recent build page. I would love to just keep the branch page open, and see the favicon change when a build is in progress, then reflect the succes/failure status.
