988431a872 Optimize PlayerChunkMap memory use for visibleChunks 
No longer clones visible chunks which is causing massive memory
allocation issues, likely the source of Humongous Objects on large servers.

Instead we just synchronize, clear and rebuild, reusing the same object buffers
as before with only 2 small objects created (FastIterator/MapEntry)

This should result in siginificant memory use reduction and improved GC behavior.
