c7f1cfbaaa Improve unlag exploit fix
- Check and clamp if commandTime is above serverTime (too far in future).
- Check commandTime delta before checking if above serverTime or below lastCommandTime.

3ff85c174a Finish unlag exploit fix
- Make sure cmdTime is never lower than last.
- Make sure delta doesn't exceed maxUnlag.
- Make sure latency gets clamped to maxUnlag (clamp appears to be missing in the engine).
- Only check for cmdTime if we are not discarding the cmd; previously, already processed queued cmd's got checked before being discarded.

631e6d9e17 Work in progress unlag exploit fix
Temporary lag compensation exploit fix by clamping the difference. Exploiter could carefully control the detonation time of a grenade, or alter the ability cool downs by altering the 'CUserCmd::command_time' field before sending it up.

32d28d4285 *::ProcessUserCmds rebuild
Rebuild of the 'CServerGameClients::ProcessUserCmds' and 'CPlayer::ProcessUserCmds' methods. The rebuild is pretty much identical to the original implementation, but with additional checks for the number of commands, and total commands in 'CServerGameClients::ProcessUserCmds'. In the future, additional clamps and checks between CPlayer and the recv'd UserCMD should be incorporated in these functions.

9720d8b0f1 Fix 'g_pGlobals' and 'UTIL_PlayerByIndex()'
'UTIL_PlayerByIndex' now returns the player from the edict array properly, 'g_pGlobals' had to be dereferenced twice.

1853f3d643 CPlayer: Finish user command executor
Command executor finished. Also improved the structure slightly to use CUserCmd instead of padded characters for 'm_LastCmd'.

b2ffab07c3 Fix mistake
Should be 'm_lastUCmdSimulationRemainderTime' instead of 'm_totalExtraClientCmdTimeAttempted'.
