/** @file
 *
 * @par History
 * - 2005/06/15 Shinigami: added CanMove - checks if an NPC can move in given direction
 *                         (IsLegalMove works in a different way and is used for bounding boxes
 * only)
 * - 2006/01/18 Shinigami: set Master first and then start Script in NPC::readNpcProperties
 * - 2006/01/18 Shinigami: added attached_npc_ - to get attached NPC from AI-Script-Process Obj
 * - 2006/09/17 Shinigami: send_event() will return error "Event queue is full, discarding event"
 * - 2009/03/27 MuadDib:   NPC::inform_moved() && NPC::inform_imoved()
 *                         split the left/entered area to fix bug where one would trigger when not
 * enabled.
 * - 2009/07/23 MuadDib:   updates for new Enum::Packet Out ID
 * - 2009/08/25 Shinigami: STLport-5.2.1 fix: params not used
 *                         STLport-5.2.1 fix: init order changed of damaged_sound
 * - 2009/09/15 MuadDib:   Cleanup from registered houses on destroy
 * - 2009/09/18 MuadDib:   Adding save/load of registered house serial
 * - 2009/09/22 MuadDib:   Rewrite for Character/NPC to use ar(), ar_mod(), ar_mod(newvalue)
 * virtuals.
 * - 2009/10/14 Turley:    Added char.deaf() methods & char.deafened member
 * - 2009/10/23 Turley:    fixed OPPONENT_MOVED,LEFTAREA,ENTEREDAREA
 * - 2009/11/16 Turley:    added NpcPropagateEnteredArea()/inform_enteredarea() for event on
 * resurrection
 * - 2010/01/15 Turley:    (Tomi) SaveOnExit as npcdesc entry
