NetworkBuffer now has valid parameter

Removed NetworkBuffer variable in NetworkMessage
TcpClient DataAvailable parameter type is now int32
Fixed NetworkMessage::EncododeMessage to put the size in the Buffer's header and to validate and fixed DecodeMessage to check the buffer's valid variable
Fixed some methods in TcpClientWindows
