Customer Support Widget (Powered by Jetboost)

I created a simple support widget for a client's site that didn't end up getting used, so might as well let others use it! This version is powered by Jetboost (https://www.jetboost.io/) but I'll re-create it using the Finsweet CMS Library soon. I tried to keep the styling very minimal so that you can update fairly easily for use in your sites.
