Dashy change port

[rocko-gft]

Unfortunately, the way Dashy is installed, you're unable to set the desired port.

1. Use Console
2. Traverse to /opt/dashy
3. Edit (nano, vi, etc) server.js
4. Change the 4000 to 80 on this line.
   /* Checks env var for port. If undefined, will use Port 8080 for Docker, or 4000 for metal */
   const port = process.env.PORT || (isDocker ? 8080 : 80);

Works like a charm and now I can set a domain name on my router for easy use. The biggest benefit to Dashy is the ability to point towards other services that make port changing a little or lot more difficult. Being that many routers won't allow a domain name to point at IP:PORT, Dashy is a huge help. Dashy is also one of the only Dashboards I have tried (3 or 4) that will allow the IP:PORT mapping.

Best of luck, I hope this helps a few folks.
