Centralized configuration about mcscripts

[TapeWerm]

You could make a bash script that sed's the file, or I could make a config. I've thought of it, a config would be more reliable, if I changed the unit file a sed expression could break. In systemd the only argument a service gets is its instance name, if applicable. I don't know a better way.

I'm going minimal effort. Making configuration files makes setup longer, I just show how to use sed. It's not something I'd usually recommend, but it's optional and this isn't a user-friendly tool anyways.
