                Large number of changes, could stealth code have been a seperate module? / file

                 +#include "stealth.h"
                

                Code included

                 +    if (fHelp || params.size() < 2 || params.size() > 5)
                

                Code replaced

                 -    if (fHelp || params.size() < 3 || params.size() > 6)
                 +     if (fHelp || params.size() < 3 || params.size() > 7)
                

                Code replaced

                +    int nChangePos;
                

                Code added
