// $Log: AvHWelder.cpp,v $
// Revision 1.23  2002/11/22 21:28:17  Flayra
// - mp_consistency changes
//
// Revision 1.22  2002/11/12 02:29:48  Flayra
// - Change inflictor for better logging
//
// Revision 1.21  2002/11/06 01:39:26  Flayra
// - Damage refactoring (TakeDamage assumes caller has already adjusted for friendly fire, etc.)
//
// Revision 1.20  2002/10/03 18:47:40  Flayra
// - Added heavy view model
//
// Revision 1.19  2002/09/23 22:37:04  Flayra
// - Fixed bug (typo?!) where welder was removing jetpacks (and removing marine status!)
//
// Revision 1.18  2002/08/16 02:49:45  Flayra
// - Updates to allow welder to repair buildables
// - Removed ability to repair soldier armor until it's visible
//
// Revision 1.17  2002/07/26 23:03:08  Flayra
// - New artwork
//
// Revision 1.16  2002/06/25 17:50:31  Flayra
// - Reworking for correct player animations and new enable/disable state, new view model artwork, alien weapon refactoring
//
// Revision 1.15  2002/06/03 16:39:10  Flayra
// - Added different deploy times (this should be refactored a bit more)
//
// Revision 1.14  2002/05/28 17:44:26  Flayra
// - Tweak weapon deploy volume, as Valve's sounds weren't normalized, welder clears webs now, welder no longer makes ambient hum, slight refactoring of variable names away from Valve style
//
// Revision 1.13  2002/05/23 02:32:40  Flayra
// - Post-crash checkin.  Restored @Backup from around 4/16.  Contains changes for last four weeks of development.
