Gunship 2000

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.
