Previously we would only expand the main `<noscript>` element for older browsers. This commit ensures that we expand all noscript elements on the page, including the one used by the splashscreen to hide itself on the no-js view.
All files under `app/assets/javascripts/scripts` will be run through babel, given sourcemaps, and output under `/assets/{name}.js`. This is another step towards removing our sprockets dependence.
