Executes a server command, as if typed at the console (ie "exec

executed until <b>after</b> GameDLLInit is called. If
ServerCommand is called earlier than that, the command is delayed until
then.

The sourcecode comment ("<i>passing in NULL gets the serverinfo</i>")
isn't entirely accurate. There appear to be two server-side info
buffers available, "<b>serverinfo</b>" and "<b>localinfo</b>", both
accessible from the console by those two commands, respectively.

Returns the session userid for the given player edict. As of server
x106, this is constant for the life of the player connection, and
unique for the life of the server process. Each time a client
connects, they are given a userid of 1 plus the userid of the previous
connecting client. When the server starts/restarts, the server starts
again at userid 1.

The AuthID is a way for applications/mods to get the Authentication ID
(uniqueID) for a player. The AuthID can be a WonID or a SteamID. The
function I've written returns the AuthID as a string. Calling <a
href="#GetPlayerWONId">GetPlayerWONId</a> will still work for Non-Steam
players just like it always has. If applications/mods want to get a
jump start on getting ready to support Steam players, then they can
start using GetPlayerAuthId, which will still work for Non-Steam
players, but it will give the WonID as a string instead of an unsigned
int.

Only clients playing via Steam will have SteamIDs. Clients who are not
using Steam will still have WonIDs (just like they always have). The
server now supports WonIDs\SteamIDs and banning using either of them.
WonIDs have not changed. SteamIDs use the format: STEAM_<#>:<#> where
<#> is replaced by numbers. An example SteamID would be
"STEAM_0:94534".
