 * on my wing work with individual ships who have high priority 
 * orders
 * 
 * 151   4/21/98 4:44p Dave
 * Implement Vasudan ships in multiplayer. Added a debug function to bash
 * player rank. Fixed a few rtvoice buffer overrun problems. Fixed ui
 * problem in options screen. 
 * 
 * 150   4/20/98 12:40a Allender
