This adds a proof-of-concept of `puppeteer-firefox`. This consists of two parts: - `//experimental/juggler` - patches to apply to Firefox. - `//experimental/puppeteer-firefox` - front-end code to be merged with Puppeteer. As things become more stable, we'll gradually move it out of the experimental folder.
