Update to 0.9.0-beta8 (by Rumko via private mail).

0.9.0-beta8:
- Include spamhaus_drop.dat in the source distribution. Fix installation
  issue (closes #364).

0.9.0-beta7:
- Initial SpamhausDrop plugin implementation, by
  Wes Young <wes@barely3am.com> (closes #363)
- Do not discard --root parameters if prefix is absolute.
- Python 2.4 backward compatibility fixes.
- Handle plugin loading error gracefully.
- Improve WormPlugin accuracy, and make it carry a reference to the
  initial event. The plugin used to alert when seeing an alert to a
  given target, and this same alert going back to the source. This can
  happen in a number of case (example: Netbios alert triggered by Snort)
  As of now, the plugin will wait for the events to be repeated against
  at least 5 differents hosts.
- Dshield CorrelationAlert now handle multiples events. Previously, we
  used to generate a single Dshield CorrelationAlert for each events
  where the source address would match the Dshield database. The plugin
  now generate CorrelationAlert for multiples events received from the
  same source.
