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 World Time Updates
Splits time updates into incremental updates as well as does
the updates per world, so that we can re-use the same packet
object for every player unless they have per-player time enabled.
