    Better High Ping Kicker (c) 2009 by Lev
    This file is provided as is (no warranties).

    URL: http://forums.alliedmods.net/showthread.php?t=85911

    This is mainly a modification of HPK by DynAstY.
    Thanks to all other HPK authors (OLO, DynAstY, shadow, EKS) - your plugins provided the base.

    Features:
        Players with immunity and slot reservations won't be checked.
        At night max ping defined by different CVAR (so usually it will be higher).
        By default keeps min 3 players (bots and hltv are not included) at server if they are not exceed night max ping twice.
        Player is banned for 1 minute, not just simply kicked.

    CVARs (Supplied values are defaults):
        hpk_ping_max 175; maximim ping to check for at day time
        hpk_ping_max_night 300; maximim ping to check for at night time
        hpk_ping_time 10; interval at which ping will be checked
        hpk_ping_tests 5; number of violations of maximum ping at which to kick
        hpk_min_players 3; don't kick player if there is this count or less players (bots and hltv are not included) at server and player's ping doesn't exceed night ping twice.
        hpk_night_start_hour 3; night period start hour (hour included)
        hpk_night_end_hour 9; night period end hour (hour excluded)

    How it is different from other HPK plugins:
        using pointers to CVARs;
        code flow is optimized;
        there is night period when ping defined by different CVAR, period also defined by CVARs;
        changes to max pings applies immediately;
        immunity for admins and slot reservations players;
        keeps min players at server (count defined by CVAR) if their ping is not too high (double night max ping);

    ChangeLog:
        v2.4 [2009.03.01]
            Initial release.
        v2.5 [2009.10.02]
            ! Change: bots and hltv are now excluded from players count for comparision with hpk_min_players.
        v2.6 [2009.10.10]
            ! Change: changed from ban ID to ban IP.
