We should add the following logos to our site and README.md, with links. If anyone (@ArtemGovorov, @segrey?) wants to provide a tracking URL, that's cool too.

• WallabyJS for providing a WallabyJS license
• SauceLabs for providing upgraded service
• JetBrains for providing WebStorm licenses

(Future: add Discourse for donation of hosted instance, if we ever get it off the ground.)

In a separate section, we could add logos for these services we consume:

• Travis CI
• AppVeyor
• Coveralls
• Netlify
• anything else? Probot maybe?
