Test the nprogress Gatsby plugin

[bloudermilk]

A few pages on our site have very large page-data.json files, which results in a long lag time navigating to those pages from elsewhere in the site. Because we don't currently show any loading indicators, this lag feels a lot like the page is broken.

To see what I mean, click on "View All Organizations ›" on the homepage.

There is a plugin, gatsby-plugin-nprogress which automatically will show a loader whenever a user navigates to one of these pages. If it works well we should consider using it on our project.
