When you get killed or crushed you can always restore roster to state
 before last mission. But sometimes it can be usefull to restore
 perviously saved state. To "save" copy roster.dat to another direcotry.
 To restore overwrite with this copy file that curently exists in games
 dir. Thsi works for many other microprose games like f15 II.
