v2 (gulp-webdriver with WebdriverIO v4)

[christian-bromann]

some requirements:

• bump WebdriverIO version to latest
• add Babel to enable ES2016 compatible syntax (see wdio-mocha-framework as example)
• add Grunt for task management (Gulp is fine too but it is easier to just copy from existing project structures like that one above)
• instead of launching wdio as process, require the webdriverio launcher package and run wdio manually
• adapt integration tests (have at minimum a simple test run using the mocha or jasmine framework)
• integrate codeclimate (should be done by one of the maintainers)
• if website isn't updated add disclaimer with information how to use
