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] PreSpawnerSpawnEvent
+
+This adds a separate event before an entity is spawned by a spawner
+which contains the location of the spawner too similarly to how the
+SpawnerSpawnEvent gets called instead of the CreatureSpawnEvent for
+spawners.
