 * @par History
 * - 2005/02/23 Shinigami: ServSpecOpt DecayItems to enable/disable item decay
 * - 2005/04/03 Shinigami: send_feature_enable() call moved from start_client_char()
 *                         to send_start() to send before char selection
 * - 2005/04/04 Shinigami: added can_delete_character( chr, delete_by )
 * - 2005/06/15 Shinigami: ServSpecOpt UseWinLFH to enable/disable Windows XP/2003 low-fragmentation
 * Heap

 * - 2005/06/20 Shinigami: added llog (needs defined MEMORYLEAK)
 * - 2005/07/01 Shinigami: removed Check_for_WinXP_or_Win2003() and transformed call of

 *                         the packet was one to be ignored.
 * - 2005/11/28 MuadDib:   Implemented check_inactivity() function in appropriate place.
