PaperMC/Spigot-Server-Patches/Don-t-allow-entities-to-ride-themselves-572.patch
Zach Brown de6a101264 Update upstream B/CB/S
Adds /paper command for reloading the paper config.
Closes GH-639

Per-world config logging has been removed in favor of all or nothing
logging for all paper settings. I don't believe it was used enough to
warrant maintaining. If this is not the case it should be possible to
re-add it.
