Move sensitive settings into a separate file

[MilesBHuff]

My Minecraft server, Settlescape, has its configs available on GitHub. This is used both as a handy way to track and deploy changes, and as a way for our playerbase to contribute to the project.
Sometimes, though, there are settings that aren't appropriate for a public GitHub repo: API keys, license keys, database passwords, and more.

When these sensitive settings are included in the same files as the non-sensitive settings, I am forced into an awkward situation where I have uncommitable changes in version-controlled files. It would be much nicer if these sensitive settings were placed into their own separate file, as I could then .gitignore it.
At present, pushing changes to one of these limbo configs guarantees a merge conflict on the server during the subsequent pull. And when working on anything in the repo, I have to be very careful to not accidentally commit any sensitive settings. Neither of these is ideal.

The only sensitive setting I am aware of is the Discord token, but any others should move as well.
