[Vortex] Safe string functions

[Robert M. Münch]

Hi, I just scanned the vortex source code and only found one reference to  
"sprintf_s", on of the new safe *_s stdlib functions. Seeing all these  
bugger overflows etc. problems coming up every day in different apps I  
think it makes sense to make vortex lib as safe as possible.

I'm using the "Managed String Library" from CERT  
(http://www.cert.org/secure-coding/managedstring.html) and it's definetly  
a useful step.

What do you think? How about making Vortex lib safe by going through the  
code and making use of managed strings?
