Transition to Hugo Image Processing (#173)

* Update layout to use Hugo Image Processing.

Created shortcode rimg that uses the srcset attribute to display responsive images.

* Copy Static images to assets folder.

* Add image processing to missing components + Update examples

* Fix rendering in https://themes.gohugo.io/
