 * @par History
 * - 2005/11/25 MuadDib:   Added PKTBI_BF::TYPE_SESPAM: to do away with spam.
 * - 2005/11/23 MuadDib:   Altered handle_mode_set for 0x72 Packet. Nows reads
 *                         from combat.cfg for warmode_wait object. Sends the
 *                         0x77 Packet and returns 0 when out of timer.
 * - 2005/12/09 MuadDib:   Added TYPE_CLIENT_LANGUAGE for setting member uclang.
 * - 2006/05/24 Shinigami: Added PKTBI_BF::TYPE_CHARACTER_RACE_CHANGER to support Elfs
 * - 2006/05/30 Shinigami: Changed params of character_race_changer_handler()
 * - 2009/07/23 MuadDib:   updates for new Enum::Packet IDs
 * - 2009/08/14 Turley:    Added PKTBI_BF::TYPE_SCREEN_SIZE & TYPE_CLOSED_STATUS_GUMP (anti spam)
 * - 2009/09/03 MuadDib:   Relocation of account related cpp/h
 * - 2009/09/03 MuadDib:   Relocation of multi related cpp/h
 * - 2009/09/06 Turley:    Changed Version checks to bitfield client->ClientType
 *                         Added 0xE1 packet (UO3D clienttype packet)
 * - 2009/11/19 Turley:    ssopt.core_sends_season & .core_handled_tags - Tomi
 * - 2009/12/03 Turley:    toggle gargoyle flying support
