Security Onion 20120113 now available!

Security Onion 20120113 is now available!  This resolves the following issues:

Issue 147: Bro 2.0 integration

Issue 185: Syntax error clearing sensor data

Note that this is just the initial integration of Bro. In the future, we'll switch Sguil's http_agent to use Bro's http.log and we'll also look at using Barnyard2 to send IDS alerts to Bro to give it a better understanding of your network.
