Add video to website

I continue to hear from the Mikva Challenge JJC that they want to see more photos and videos on Expunge.io to make it more engaging. 

JJC & Smart Chicago created this video as an outreach: https://www.youtube.com/watch?v=aNTu6SrZGLY&feature=youtu.be

This can probably live on Expunge.io (either the homepage or the About page makes the most sense to me).
