Multiple things

Change initialize...Session to only be extra. New get...NetworkComponent methods in Protocol
Remove toEntity in EntitySnapshots, instead use them as a constructor argument
PlayerNetworkComponent goes in SpoutPlayer constructor
setupInitialChunk in SpoutEntity always is LOAD_GEN for the region
remove the connect(...) method in SpoutPlayer; when a player is created is ALWAYS online; it can later become offline
