Server Side Chunk Generation

* Server World Class
* WorldGenStream class to handle multithreaded map generation
* ServerPlayer stores active chunk boundaries

* BlockChunk stores position
* Renamed client World to LocalWorld
* Disabled client side Generation
* ServerConnection stores chunk packets to be used by the GameScene,
  which gives them to the world (change later?)

* Reenabled "BlockChunk Packet Encoding" test in tests/BlockChunk.cpp
