P0-A11: Part 971: Server, Improvements

I am in the process of rewriting the server system to use syncvars rather than commands to update the state of connected players.

Previously, I was updating the state of these clients by sending messages in a loop, but this very quickly overwhelms the network when the user count increases.

Using syncvars to sync the data is the correct way, but this will involve extensive changes and improvements to my code.

So far, I have a proof of concept working, and I next need to integrate this with my existing system.
