Add testing suite for Web Components

[Nevraeka]

Add web-components-tester npm module and setup scripts and files for easy unit and functional tests. Integrate with Divshot/Travis if possible.

@Nevraeka @DannyBlueDesign - This branch is the start for the web component testing. Read the commit message and see that we will need to determine how to handle the selenium/safari issues that come up when running the test. More to be added with Mocha/Chai

Added wrong issue reference.

So, once we complete the issue #21 the test cases will be in the project directory.

I still cant figure out how to integrate it with Divshot/Travis. Need more time XD
