Zach Brown 70ce6ce831
Move version command update checking to the implementation
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.

Subject: [PATCH] Optimize RegistryMaterials
Use larger initial sizes to increase bucket capacity on the BiMap
BiMap.get was seen to be using a good bit of CPU time.
