* Changes in NetworkManager:
- Removed the exception throwing when a socket is disconnected and replaced it with a warning log message as it's not feasible to try/catch every time a packet is sent out
- Sequence numbers can automatically be set when sending out raw bytecode packets
- The sequence number has a lock now to prevent a very rare race condition
