Major updates to most network classes.
Simplify CNetServer so it doesn't duplicate any client behaviour; all
players now run CNetClient.
Remove most player/slot management from networking code.
Wait for all players to finish loading before starting the simulation.
Remove CGameAttributes; attributes are now just a JS object.
Remove CPlayer; they are now just simulation entities.
Handle player colours via simulation system.
Add a default map for Atlas, so it always has something to load.
Move network documentation to Doxygen.
Remove lots of now-unused code.
This was SVN commit r7653.
Don't flush network queue after every message.
Desingletonify CGameAttributes to allow testing.
Make network server/client basically testable.
Add very basic tests for network server/client.
Fix FsmActionCtx memory leak.
Split CNetHost into a separate file.
Convert CNetHost, CNetSession to a more conventional coding style.
Delete CNetLogger, since it's a lot of complexity and is barely used and
is redundant with CLogger.
Other minor simplifications.
This was SVN commit r7623.
Add new turn manager that should be more correct and potentially more
efficient.
Remove evil CNetServer/CNetClient multiple inheritance of CTurnManager.
Add multiplayer autostart.
Various minor cleanups.
This was SVN commit r7551.
