// Revision 1.42  2002/11/22 21:25:46  Flayra
// - Adminmod fixes
//
// Revision 1.41  2002/11/15 04:42:13  Flayra
// - Moved utility function into here from client.cpp
//
// Revision 1.40  2002/11/12 22:39:25  Flayra
// - Logging changes for Psychostats compatibility
//
// Revision 1.39  2002/11/12 02:28:53  Flayra
// - Don't reset adminmod_ entities
//
// Revision 1.38  2002/11/03 04:51:55  Flayra
// - Refactoring for AddToFullPack changes
//
// Revision 1.37  2002/10/24 21:42:12  Flayra
// - Utility function for telefragging
// - Hive technology fixes
//
// Revision 1.36  2002/10/20 21:11:34  Flayra
// - Optimizations
//
// Revision 1.35  2002/10/19 21:09:56  Flayra
// - Debugging info for linux
//
// Revision 1.34  2002/10/19 20:58:31  Flayra
// - Debugging info for linux
//
// Revision 1.33  2002/10/18 22:22:19  Flayra
// - Sensory chamber triggers vocal alert
//
// Revision 1.32  2002/10/16 01:06:33  Flayra
// - Added generic particle event
// - Visibility tweak: enemies aren't "detected" unless they're moving.  This means the commander can only see nearby moving blips, and marines with motion-tracking won't see still aliens that are detected because they're nearby.  This also means webs won't show up when nearby.
// - Distress beacon event
//
// Revision 1.31  2002/10/07 17:49:23  Flayra
// - Umbra balance change
//
// Revision 1.30  2002/10/03 19:06:50  Flayra
// - Profiling info for Linux build
//
// Revision 1.29  2002/09/23 22:30:05  Flayra
// - Commander dropped weapons live forever
// - Observatory and sensory chambers check range in 2D for commander regions
// - Added turret factory upgrading (for siege)
//
// Revision 1.28  2002/09/09 20:05:59  Flayra
// - Sensory chambers now detect enemies in range
//
// Revision 1.27  2002/08/31 18:01:03  Flayra
// - Work at VALVe
//
// Revision 1.26  2002/08/16 02:44:11  Flayra
// - New damage types
//
// Revision 1.25  2002/08/09 00:52:14  Flayra
// - Removed old #ifdef
//
// Revision 1.24  2002/08/02 21:50:24  Flayra
// - Removed hives-are-visible code, I think it's safe again
//
// Revision 1.23  2002/07/25 16:58:00  flayra
// - Linux changes
//
// Revision 1.22  2002/07/23 17:24:27  Flayra
// - Added random building angles for diversity, added research started hooks for distress beacon effects, added versatile alien tech tree, hives are always visible, observatories detect nearby aliens, umbra blocks most but not all bullets
//
// Revision 1.21  2002/07/08 17:16:43  Flayra
// - Tried to cut down on sound list spam by defaulting to CHAN_BODY, added debugging code for tracking down solidity issues
//
// Revision 1.20  2002/07/01 21:44:58  Flayra
// - Added primal scream and umbra support
//
// Revision 1.19  2002/06/25 18:16:56  Flayra
// - Quieted construction effects (normalized now), temporarily removed sensory chamber sight, added upgrading of armory, wrapped bullet tracing for umbra
//
// Revision 1.18  2002/06/03 16:57:44  Flayra
// - Toned down carapace and marine upgrades, removed redundant hive class name, all buildables are subject to visibility rules
//
// Revision 1.17  2002/05/28 18:13:50  Flayra
// - Sensory chambers contribute to hive sight
//
// Revision 1.16  2002/05/23 02:33:20  Flayra
// - Post-crash checkin.  Restored @Backup from around 4/16.  Contains changes for last four weeks of development.
