This gives greater flexibility and stops some of those especially
annoying bugs

This helps make sure that missed packets don't cause jitter or waste CPU

Previously, everyone thought everyone was master, and it resulted in you
controlling each player. Now you are only the master of /your/ player,
so multiplayer works as expected.

This is the real initial commit with all the code I have until now.

Networking: A server and 2 clients connect and then control their
players. This is still buggy. For example, every client controls the
/same/ player.

FPS controls: WSAD, Jump, and Look with mouse are all implemented (Taken
from Caliou's demo). This includes collisions.

A team game with an emphasis on movement (with no shooting), inspired by
Overwatch and Zineth
