 * Initial revision
 *
 * 
 * 23    10/25/99 5:51p Jefff
 * commented some scoring debug code
 * 
 * 22    10/15/99 3:01p Jefff
 * scoring change in coop and tvt.  for big ships, killer gets 100% of
 * score, but teammates also get 50%.
 * 
 * 21    9/12/99 9:56p Jefff
 * fixed another cause of the
 * medals-in-training-missions-not-getting-recorded bug
 * 
 * 20    9/10/99 9:44p Dave
 * Bumped version # up. Make server reliable connects not have such a huge
 * timeout. 
 * 
 * 19    9/05/99 11:19p Dave
 * Made d3d texture cache much more safe. Fixed training scoring bug where
 * it would backout scores without ever having applied them in the first
 * place.
 * 
 * 18    8/26/99 8:49p Jefff
 * Updated medals screen and about everything that ever touches medals in
 * one way or another.  Sheesh.
 * 
 * 17    8/22/99 5:53p Dave
 * Scoring fixes. Added self destruct key. Put callsigns in the logfile
 * instead of ship designations for multiplayer players.
 * 
 * 16    8/22/99 1:19p Dave
 * Fixed up http proxy code. Cleaned up scoring code. Reverse the order in
 * which d3d cards are detected.
 * 
 * 15    8/17/99 1:12p Dave
 * Send TvT update when a client has finished joining so he stays nice and
 * synched.
 * 
 * 14    8/06/99 9:46p Dave
 * Hopefully final changes for the demo.
 * 
 * 13    7/30/99 7:01p Dave
 * Dogfight escort gauge. Fixed up laser rendering in Glide.
 * 
 * 12    4/30/99 12:18p Dave
 * Several minor bug fixes.
 * 
 * 11    4/28/99 11:13p Dave
 * Temporary checkin of artillery code.
 * 
 * 10    3/01/99 10:00a Dave
 * Fxied several dogfight related stats bugs.
 * 
 * 9     2/26/99 4:14p Dave
 * Put in the ability to have multiple shockwaves for ships.
 * 
 * 8     2/23/99 2:29p Dave
 * First run of oldschool dogfight mode. 
 * 
 * 7     2/17/99 2:11p Dave
 * First full run of squad war. All freespace and tracker side stuff
 * works.
 * 
 * 6     1/29/99 2:08a Dave
 * Fixed beam weapon collisions with players. Reduced size of scoring
 * struct for multiplayer. Disabled PXO.
 * 
 * 5     1/12/99 5:45p Dave
 * Moved weapon pipeline in multiplayer to almost exclusively client side.
 * Very good results. Bandwidth goes down, playability goes up for crappy
 * connections. Fixed object update problem for ship subsystems.
 * 
 * 4     10/23/98 3:51p Dave
 * Full support for tstrings.tbl and foreign languages. All that remains
 * is to make it active in Fred.
 * 
 * 3     10/13/98 9:29a Dave
 * Started neatening up freespace.h. Many variables renamed and
 * reorganized. Added AlphaColors.[h,cpp]
