#61 scan failure on BSD systems with verbose syslogd

[Nick Hilliard]

On BSD systems where syslogd is configured with the "-v" or "-vv" options, the log file format is changed slightly to include the message facility and priority. This causes the __prefix_line regex not to recognise valid syslog entries.

Standard syslog format example:
May 25 13:38:00 hostname sshd[27435]: Invalid user testuser from 192.168.6.3

Verbose syslog format example:
May 25 13:38:00 <auth.info> hostname sshd[27435]: Invalid user testuser from 192.168.6.3

I've attached a fix to support both modes.
