// Project: Nostril (aka Postal)
// 
// History:
//		04/08/97 JMI	Started.
//
//		05/25/97	JMI	Integrated newest TCP/IP CNetServer/Client interface.
//							Still need to detect when the game is starting.
//							GUI could still use a little cleaning up.
//
//		05/26/97	JMI	Removed psNumPlayers and psMyPlayerNum parameters.
//
//		06/13/97 MJR	Changed function prototypes.
//
//		06/16/97 MJR	Added use of watchdog timer for network blocking callbacks.
//
//		08/02/97	JMI	Added an icon to watchdog timer for network blocking
//							callbacks and made it generally callable.
//
//		08/10/97 MJR	Added browse parameter to DoNetGameDialog().
//
//		08/27/97	JMI	Changed NetProbIcons functions to NetProbGui functions.
//							Also, instead of a DrawNetProbGui() there's a 
//							GetNetProbGui() so you can draw it, move it, change the
//							text, etc.
