[TB] Add Netlify badge to application

[aaronreed708]

Problem/Concern

According to https://www.netlify.com/legal/open-source-policy/, we need to add the Netlify badge to our application that, when clicked, will link the user to https://www.netlify.com. The open source policy link gives examples of projects that do so. We can use one of their badges or one of our own.

@lwnoble do you have a suggestion of where to put it? Pre-made badges are here: https://www.netlify.com/press/#badges (search for "netlify badges" in the page, reference is broke). The examples I see show it in the footer, but we don't have a footer.
