This makes it easier for downstream projects (forks) to replace the version fetching system with their own. It is as simple as implementing an interface and overriding the default implementation of org.bukkit.UnsafeValues#getVersionFetcher() It also makes it easier for us to organize things like the version history feature. Lastly I have updated the paper implementation to check against the site API rather than against jenkins.
