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] Use Log4j IOStreams to redirect System.out/err to logger
Log4j2 provides an optimized implementation of PrintStream that
redirects its output to a logger. Use it instead of a custom
implementation for minor performance improvements and some fixes.
With the old implementation, each call to System.print()
results in a separate line, even though it should not result in
a line break. Log4j's implementation handles it correctly.
