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] Hook into CB plugin rewrites
Allows us to do fun stuff like rewrite the OBC util fastutil location to
our own relocation. Also lets us rewrite NMS calls for when we're
debugging in an IDE pre-relocate.
