// Revision 1.23  2002/11/22 21:28:16  Flayra
// - mp_consistency changes
//
// Revision 1.22  2002/10/18 22:19:22  Flayra
// - Fixed bug where HMG never ran out of ammo
//
// Revision 1.21  2002/10/16 20:53:09  Flayra
// - Removed weapon upgrade sounds
//
// Revision 1.20  2002/10/16 00:56:44  Flayra
// - Removed velocity change and ground restrictions (too confusing and felt buggy)
//
// Revision 1.19  2002/10/03 18:46:20  Flayra
// - Added heavy view model
//
// Revision 1.18  2002/09/23 22:16:31  Flayra
// - HMG can only be fired from the ground, and slows down firer
//
// Revision 1.17  2002/08/09 01:02:00  Flayra
// - Made HMG faster to deploy
//
// Revision 1.16  2002/07/24 19:09:16  Flayra
// - Linux issues
//
// Revision 1.15  2002/07/24 18:45:41  Flayra
// - Linux and scripting changes
//
// Revision 1.14  2002/07/08 16:59:48  Flayra
// - Updated anims and timing for new artwork
//
// Revision 1.13  2002/07/01 21:33:06  Flayra
// - Tweaks for new artwork
//
// Revision 1.12  2002/06/25 17:50:59  Flayra
// - Reworking for correct player animations and new enable/disable state, new view model artwork, alien weapon refactoring
//
// Revision 1.11  2002/06/03 16:37:31  Flayra
// - Constants and tweaks to make weapon anims and times correct with new artwork, added different deploy times (this should be refactored a bit more)
//
// Revision 1.10  2002/05/28 17:44:58  Flayra
// - Tweak weapon deploy volume, as Valve's sounds weren't normalized
//
// Revision 1.9  2002/05/23 02:33:42  Flayra
// - Post-crash checkin.  Restored @Backup from around 4/16.  Contains changes for last four weeks of development.
