 * Fixed up Netgame.respawn for the standalone case.
 * 
 * 13    4/06/98 6:37p Dave

 * Fixed oberver hud problems. Put in handy netplayer macros. Reduced size
 * of network orientation matrices.
 * 
 * 8     3/12/98 10:45p Allender
 * more ingame join stuff.  Mission events are not evaluated during
 * critical ingame portion.  Wings/ships appear to work great.  Support
 * ships still has a few problems I think 
 * 
 * 7     3/12/98 5:45p Dave
 * Put in new observer HUD. Made it possible for observers to join at the
 * beginning of a game and follow it around as an observer full-time.
 * 
 * 6     3/05/98 5:03p Dave

 * weapon select.
