Move to localhost:8080

Move to localhost so that the project works without needing to setup any local DNS services.
We should use localhost:8080 as port 80 is reserved and will need root access on some systems and simply not work at all on others.

This also requires moving to nginx, as Apache can't handle HTTP and HTTPS on the same port in any way.

On nginx, we need to investigate if we can support HTTP and HTTPS directly on the same port:

Otherwise, we will need to create a redirect when connecting to the wrong port for the desired protocol.
