Another attempt at unload queue, including EAR improvements.

Quellcode durchsuchen 
should be fully working now as I pretty much fell back to existing
methods so anything touching the unloadQueue set should behave correctly.

And maintained NMS Reflection safe change too

Subject: [PATCH] Optimize Chunk Unload Queue
@ -20,8 +20,10 @@ We mark the chunk as active in many places that notify it is still being used, s
when the chunk unload queue reaches that chunk, and sees the chunk became active again,
it will skip it and move to next.
Also optimize EAR to use these methods.
