Add link in "hamburger" menu to Lychee service

We should add a link in the hamburger menu to the Lychee service. The Lychee service will be running on a dedicated port, but behind NGINX, so we can just route the link to "albums.idaho4h.com" or whatever.

Actually, I really like that domain. "albums.idaho4h.com"

• Make the link button
• Configure NGINX to route "albums.idaho4h.com" to the Lychee service
