feat(cdn): introduce dist folder for CDN artifacts (#682)

* chore(gulp): clean up of gulp tasks

* feat(cdn): introduce CDN artifacts

This introduces a new `dist` folder, which includes artifacts that can
be manually included in a project, or hosted on a CDN. Each component
folder has its own artifact that can be used, e.g. accordion.min.js.

* chore(prettier): adding `dist` folder to prettierignore

* fix(cdn): updating cdn links in code example
