Add a way to open CI services too

[davegaeddert]

A cool addition I think would be to add a way to quickly open a few other websites related to a repo:

• Dependencies.io
• PullApprove?
• Travis CI
• Circle CI
• Dockerhub

I haven't mocked this up yet, but I'm imagining that floated on the right side of the text input box could be an icon for each service that the repo is using (parsed from README badges or config file existence). So by default, you'd have a little GitHub icon which is highlighted, but if you use TravisCI for example then that icon would be greyed out next to it. Haven't tried this yet, but I'm imagining you could arrow left and right to open a specific service -- I don't think you really need the left and right arrows when typing because it's usually so short (and usually use backspace).
