phantomjs replacement

[benhalverson]

Any plans to replace phantomjs with the chrome version of a headless browser? puppeteer
Reasons:

• doesn't screenshot videos tags
• issues with getting italic fonts to show properly
• maintainer stepped down

Hey @benhalverson,

With Vitaly Slobodin stepping down and headless browsing being available in Chrome(v59 I think?), we'll definitely want to start moving away from phantomjs. I'm going to mark place this in the v2.0.0 milestone as this will definitely be a breaking update.
