Network

The networking has been optimized since v0.1.2, we are not serializing the entire game instance, we are sending only the needed data, thanks to the linker by making the class field names more friendly.

2 Players playing an hour:
- Each player uploads 200 B/packet * 5 packets/s = 1kB/s
- Total download and upload(SEPARATELY) = (200 * 5 * 2 * 60 * 60) / 1000000 = 7.2 MB/hour
