Electron and selenium Webdriver setup

[Temi89]

I updated the runtime directory to include an electronDriver following the examples for using electron with selenium .

Links : https://github.com/electron/electron/blob/master/docs/tutorial/using-selenium-and-webdriver.md

To get sample apps you can run electron packager on any of the samples to generate Myapp directory : https://github.com/hokein/electron-sample-apps
