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] Lazy init world storage in CraftOfflinePlayer
Allows access to some offline player properties even when there are no
worlds loaded. This is typically a rare occurrence but probably one that
should be covered as best we can.
