// Revision 1.14  2002/11/22 21:28:17  Flayra
// - mp_consistency changes
//
// Revision 1.13  2002/10/18 22:23:24  Flayra

//
// Revision 1.12  2002/07/24 19:09:18  Flayra
// - Linux issues
//
// Revision 1.11  2002/07/24 18:55:53  Flayra

//
// Revision 1.10  2002/07/24 18:45:43  Flayra
// - Linux and scripting changes
//
// Revision 1.9  2002/07/08 17:23:03  Flayra
// - Don't allow builder to web a player by hitting him
//
// Revision 1.8  2002/06/25 17:50:07  Flayra
// - Some refactoring, new view model, removed old code, no longer costs resources to use, web projectile can ensnare marines without creating web
//

// - New level 2 view model
//
// Revision 1.6  2002/06/03 16:39:10  Flayra
// - Added different deploy times (this should be refactored a bit more)
//
// Revision 1.5  2002/05/28 18:13:37  Flayra
// - Limit total webs, limit webs in sphere
//
// Revision 1.4  2002/05/23 02:32:39  Flayra
// - Post-crash checkin.  Restored @Backup from around 4/16.  Contains changes for last four weeks of development.
