Move Javascript files from app/components/**/*.js back to app/javascript/src/javascripts/*.js.
This way Javascript files are in one place, which simplifies import paths and makes it
easier to see all Javascript at once.
Components are used to encapsulate common UI widgets used throughout the site. This includes things like comments, tag
lists, post thumbnails, paginators, and other things used repeatedly throughout the site. Components encapsulate a
widget's HTML, CSS, and Javascript together so that all the code for a component is in a single place.
