Fixed a bug relating to custom-elements's first vnode where render(){ return <div class="example" /> } would set the example-class on the custom-element itself.

Added support for className and style similar to react
Cleaned up some comments
Reworked how tests are built in order to add a new test "pdf" which was a small side-project where previous mentioned bug showed up, it's an example using HTML to create a PDF for printing
