Subject: [PATCH] Paper Metrics

Removes Spigot's mcstats metrics in favor of a system using bStats

To disable for privacy or other reasons go to the bStats folder in your plugins folder
and edit the config.yml file present there.

Please keep in mind the data collected is anonymous and collection should have no
tangible effect on server performance. The data is used to allow the authors of
PaperMC to track version and platform usage so that we can make better management
decisions on behalf of the project.
