Bro git/webserver updates

Hi,

I will be updating the Bro git/webserver. There might be intermittent
outages in the next few hours (mostly of git - the webserver should
automatically fail over).

After a brief fight with httpd (the old config file did not work without
changes), everything seems to be up and working again.

Please let me know if you notice/encounter any problems.
