bdbdbe44 SPIGOT-5024: Fox error - Unknown target reason
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.
light queue is actually buggy, so re-enabling the config.
however, if anyone is ok with the buggy behavior, made the max time lost due to
light queue configurable.
We want to get to making the ligth queue default if we can make it work perfectly.
also applying neighbor optimizations to use the faster method for light checks.
