Subject: move server config to easy to extend style (#71)

Move servers to new configuration style.

I will probably cover this in a new shorter video, or maybe in combination with something else.
This should hopefully remove  getting so many people making issues about LSPs that they don't want to.

I can update documentation if what is happening is not clear.
