[PATCHed] A few little changes involving long_options in nmap.cc

[Kris Katterjohn <katterjohn () gmail com>]

The attached patch (/nmap SVN revision 4342) uses strcmp() to check for
--script and --open, and optcmp() for --ip-options (now --ip_options works).

I kinda messed up the log for this revision (oops!), which is one of the
reasons I'm sending this to the list.

Thanks,
Kris Katterjohn
