NIOM - NIO Manager

Alternative to Netty
improve the existing network manager using Blocking NIO instead of IO (more effecient code)
Writes use a direct memory buffer for zero copy writes, more stable memory usage.

Reimplement Low Priority Queue
Optimized Packet PacketQueue System that supports instant send notification to the writer thread
Removed packet queue walking since it will very unlikely ever be hit now.
Writer thread will now stay asleep until it has work to do
Network threads are no longer interrupted every tick, letting them sleep as much as possible
