Patch a publically disclosed XSS vuln in Nova (also random compatibility bug in pcap)

I couldn't figure out if you're working off the Master or Integration branch, since they seem out of sync and they both have unique/new commits in them... so I branched off Integration.

Fixed an XSS vuln I saw disclosed on the seclist forums. See commit messages for details. Also fixed a compatibility bug with the newer version of libpcap so I could get it to run on the newer Ubuntu versions.
