FYI: Running E2E Tests requires updated packages

[selangley-wa]

I cloned this repo because I was interested in the E2ETest project that starts and stops a dotnet application as part of the test run. (Thanks for that!)

In order to get it to run on my current system,

1. Updated the packages nightwatch and selenium-server-standalone-jar to their latest versions.

2. Downloaded a newer version of the selenium chrome driver from https://sites.google.com/a/chromium.org/chromedriver/downloads to match my currently installed chrome and pointed to it in the file:

   BlogPlayground.E2ETest/nightwatch.config.js

3. Finally, I added this config variable to the chromeOptions in that same file to stop warnings generated with the newer version of nightwatch.js

   "w3c": false

Thanks for letting me know, do you want to send a PR?
If not, I will try to fix as soon as I can
