Faking PhantomJS's userAgent in Nightwatch.js

While working on some odd behavior with a PhantomJS driven Nightwatch.js test I had a need to change the userAgent that PhantomJS was reporting. Turns out there is a simple way to do this in the configuration file:

"desiredCapabilities": {
    "browserName": "phantomjs",
    "javascriptEnabled": true,
    "acceptSslCerts": true,
    "phantomjs.page.settings.userAgent": "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/37.0.2062.120 Safari/537.36"

I suspect a similar technique can be used for many of the PhantomJS settings.
