[PATCH] Add more PCRE flags for NSE pcre.flags()

[Kris Katterjohn <katterjohn () gmail com>]

Hey everyone!

I've attached a patch to add more PCRE flags for the NSE pcrelib 
function pcre.flags(), which returns a table of the PCRE flags available 
for your system.  Now the list is up-to-date with libpcre 7.6 (most of 
these option have been around for at least a few past versions--all were 
available in 7.4).

Since I'm not aware of any particular libpcre version requirements, I've 
surrounded my additions with #ifdef's.

Since my additions pick up where the previous list left off, I'm 
guessing they weren't left out for any particular reason (probably not 
available at the time of writing pcrelib).  However, I'd like a go from 
Fyodor or Diman before adding it.

Any comments are appreciated.

Thanks,
Kris Katterjohn
