[bug-cgicc] 64bit bug in multipart/formdata uploads

[Jim Hull]

This is a simple string::size_type vs u_int bug I found today while 
testing our tools on a 64bit platform.

inside extractBetween(), 'start' is declared as 'unsigned int' and then 
tested against std::string::npos, which on a 64bit system will always be 
false.

Iv'e attached a patch with the fix.

Thanks!
