[Bro] Bro detection scripts

since the ftp bruteforcing / ssh password guessing scripts are policy
scripts, they are not loaded by default.

If you invoke bro via command-line, just add
protocols/ssh/detect-bruteforcing.bro and
protocols/ftp/detect-bruteforcing.bro to your command line. If you use
broctl, the ssh bruteforce detector should be loaded by default; you have
to add the ftp one to local.bro.

If the notices still do not show up afterwards, you might need to tweak
the thresholds of the different scripts.

I hope this helps,
