// Revision 1.12  2002/11/22 21:26:06  Flayra
// - Fixed turret factory abuse, where turrets became active after recycling the nearby turret factory before turret was fully contructed.
// - Fixed bug where siege turrets became re-activated after building a regular turret factory nearby.
// - mp_consistency changes
//
// Revision 1.11  2002/11/12 02:29:11  Flayra
// - Removed check for mp_testing with siege
//
// Revision 1.10  2002/11/03 04:52:18  Flayra
// - Removed server variables, hard-coded them
//
// Revision 1.9  2002/10/16 01:07:36  Flayra
// - Removed unused sounds
//
// Revision 1.8  2002/09/23 22:32:14  Flayra
// - Removed minimum range for siege
//
// Revision 1.7  2002/08/16 02:48:09  Flayra
// - New damage model
//
// Revision 1.6  2002/07/26 23:08:14  Flayra
// - Siege don't fire at babblers
//
// Revision 1.5  2002/07/24 18:55:52  Flayra
// - Linux case sensitivity stuff
//
// Revision 1.4  2002/07/23 17:27:47  Flayra
// - Siege no longer requires LOS (so it's actual siege)
//
// Revision 1.3  2002/07/01 21:47:27  Flayra
// - Added siege shockwave effect, added view shaking effects
//
// Revision 1.2  2002/05/28 18:07:19  Flayra
// - Reduced tracking rate for siege
//
// Revision 1.1  2002/05/23 02:33:20  Flayra
// - Post-crash checkin.  Restored @Backup from around 4/16.  Contains changes for last four weeks of development.
