Spy Disguise Selector
This is an TFC spy script made by Koron from TFFF (http://www.planetfortress.com/tfff)
It has four different CFG files for it. If you use this, you'll 
probably want to put the command "-zone 512" in your command line for Half-Life. If you don't, 
HL may give you a Z_malloc error, which will exit Half-Life. Use "<" and ">" to select which class 
you want to disguise as, then press "/" to disguise.
