// Revision 1.17  2002/10/16 01:02:16  Flayra
// - Added commander hacking particle effect, but it doesn't seem to play or be visible
//
// Revision 1.16  2002/10/03 18:59:46  Flayra
// - Reworked orders
//
// Revision 1.15  2002/09/25 20:49:04  Flayra
// - Removed use order
//
// Revision 1.14  2002/08/02 21:53:18  Flayra
// - Added type to the order, so help can be displayed on the client
//
// Revision 1.13  2002/07/24 18:45:42  Flayra
// - Linux and scripting changes
//
// Revision 1.12  2002/05/23 02:33:20  Flayra
