This system can easily be extended by independent authors without collisions, something the old system with plain increasing integers did not allow. Do this by utilizing the previously unused message code `NETMSG_NULL` which has a value of 0. This works for engine and game messages, snapshot items and events.

Client -> INFO -> Server

Contains version info, name, and some other info.

Client <- MAP <- Server
|
|
Contains current map.
|
|
|
|
Client -> READY -> Server
|
|
The client has loaded the map and is ready to go,
|
|
but the mod needs to send it's information aswell.
|
|
modc_connected is called on the client and
|
|
mods_connected is called on the server.
|
|
The client should call client_entergame when the
|
|
mod has done it's initilization.
|
|
|
|
Client -> ENTERGAME -> Server
|
|
Tells the server to start sending snapshots.
|
|
client_entergame and server_client_enter is called.
