Title: Adding progress indicator to pages loaded via Turbolinks.

Turbolinks alone does not provide any visual indication that a page is loading.
We want to improve the user experience for those waiting for pages to load. This fixes that.

**Developer Notes:** Added Gem dependency on nprogress-rails.
