Update for Update for Firehol's get-iana.sh script

No, the title isn't a typo. The firehol mailing list received an update from ktsaou, the creator of firehol that the update had already been implemented in the CVS. I just wish that the changes would actually make it to release instead of just sitting inside of a CVS that seemingly no one checks. Enough of my little rant. If you want the updated version, you can get it from the CVS.
