Optimize Light Engine
Massive update to light to improve performance and chunk loading/generation.

1) Massive bit packing/unpacking optimizations and inlining.
  A lot of performance has to do with constant packing and unpacking of bits.
  We now inline a most bit operations, and re-use base x/y/z bits in many places.
  This helps with cpu level processing to just do all the math at once instead
  of having to jump in and out of function calls.

  This much logic also is likely over the JVM Inline limit for JIT too.
2) Applied a few of JellySquid's Phosphor mod optimizations such as
  - ensuring we don't notify neighbor chunks when neighbor chunk doesn't need to be notified
  - reduce hasLight checks in initializing light, and prob some more, they are tagged JellySquid where phosphor influence was used.
3) Optimize hot path accesses to getting updating chunk to have less branching
4) Optimize getBlock accesses to have less branching, and less unpacking
5) Have a separate urgent bucket for chunk light tasks. These tasks will always cut in line over non blocking light tasks.
6) Retain chunk priority while light tasks are enqueued. So if a task comes in at high priority but the queue is full
   of tasks already at a lower priority, before the task was simply added to the end. Now it can cut in line to the front.
   this applies for both urgent and non urgent tasks.
7) Buffer non urgent tasks even if queueUpdate is called multiple times to improve efficiency.
8) Fix NPE risk that crashes server in getting nibble data

Unload leaked Cached Chunks
Due to some complexity in mojangs complicated chain of juggling
whether or not a chunk should be unloaded when the last ticket is
removed, many chunks are remaining around in the cache.

These chunks are never being targetted for unload because they are
vastly out of view distance range and have no reason to be looked at.

This is a huge issue for performance because we have to iterate these
chunks EVERY TICK... This is what's been leading to high SELF time in
Ticking Chunks timings/profiler results.

We will now detect these chunks in that iteration, and automatically
add it to the unload queue when the chunk is found without any tickets.

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.
