Saturday, December 11, 1993 10:25:55 AM

Friday, September 30, 1994 5:48:25 PM (Jason)
	moved nearly all sounds out of the damage_definition structure and into shapes.
Wednesday, October 26, 1994 3:18:59 PM (Jason)
	invincible players are now damaged by fusion projectiles.
Wednesday, November 30, 1994 6:56:20 PM  (Jason)
	oxygen is used up faster by running and by firing.
Thursday, January 12, 1995 11:18:18 AM  (Jason')
	dead players donÕt continue to use up oxygen.
Thursday, July 6, 1995 4:53:52 PM
	supports multi-player cooperative games. (Ryan)

Feb 4, 2000 (Loren Petrich):
	Added SMG wielding stuff

	Changed halt() to assert(false) for better debugging

Feb 18, 2000 (Loren Petrich):
	Added support for a chase cam.
	Note that mark_player_collections() always loads the player sprites
	in expectation of a chase cam; this could be made to conditional on
	whether a chase cam will ever be active.

Feb 21, 2000 (Loren Petrich):
	Changed NO_TELEPORTATION_DESTINATION to SHRT_MAX, an idiot-proof value,
	since there are unlikely to be that many polygons in a map.
	
	Added upward and rightward shifts of the chase-cam position

Feb 25, 2000 (Loren Petrich):
	Moved chase-cam data into preferences data; using accessor in "interface.h"
	Made it possible to swim under a liquid if one has the ball

Feb 26, 2000 (Loren Petrich):
	Fixed level-0 teleportation bug; the hack is to move the destination
	down by 1.
	
	Added chase-cam reset feature, for the purpose of doing chase-cam inertia.
	The reset is necessary to take into account teleporting or entering a level.

Mar 2, 2000 (Loren Petrich):
	Moved the chase-cam stuff into ChaseCam.c/h
	
Mar 22, 2000 (Loren Petrich):
	Added a function to revive_player() to reset the field of view properly
	when reviving

May 14, 2000 (Loren Petrich):
	Added XML-configuration support for various player features

May 22, 2000 (Loren Petrich):
	Added XML configurability for the powerup durations

May 27, 2000 (Loren Petrich):
	Added oxygen depletion and replenishment rates

Jun 11, 2000 (Loren Petrich):
	Pegging health and oxygen to maximum values when damaged;
	takes into account negative damage from healing projectiles.
	Also turned "agressor" into "aggressor".

Jun 15, 2000 (Loren Petrich):
	Added support for Chris Pruett's Pfhortran

Jun 28, 2000 (Loren Petrich):
	Generalized the invincibility-powerup vulnerability and added XML support for that

Jul 1, 2000 (Loren Petrich):
	Added Benad's changes

Jul 10, 2000 (Loren Petrich):
	Changed calculate_player_team() slightly; no more first vassert()

Aug 31, 2000 (Loren Petrich):
	Added stuff for unpacking and packing

Apr 27, 2001 (Loren Petrich):
	Made player guided missiles optional
        
Oct 21, 2001 (Woody Zenfell):
        Made player_shape_definitions available to the rest of the system -
        in particular, so that SDL network dialog widgets can use it to render
        player icons.

Feb 20, 2002 (Woody Zenfell):
    Ripped action_queue support out into new ActionQueues class (see ActionQueues.h)
    Providing pointer gRealActionQueues to help others find the set of queues they are
    accustomed to using.

May 20, 2002 (Woody Zenfell):
    get_ticks_since_local_player_in_terminal() mechanism

Jan 12, 2003 (Woody Zenfell):
	Single entry point (reset_action_queues()) to reset all ActionQueues that need to be reset

May 22, 2003 (Woody Zenfell):
	Fixing damaging polygon types; giving player netgame penalty feedback; announcing player
	net disconnects.

 May 27, 2003 (Woody Zenfell):
	I hear dead people.  (netmic, star protocol or newer only)

 June 14, 2003 (Woody Zenfell):
	update_players() now has a predictive mode of execution which takes many fewer actions
	(i.e. tries to alter only state like the player's location and facing etc.)

 May 21, 2004 (Alexei Svitkine):
	Made all the MML-settable stuff in this file have a ResetValues method that resets to
	old values (which we now save). Had to move some free-standing variables into structs
	for this.
