ae3ae9a75b Awful fix for SSH login detection. 
- We need a counted measure of payload bytes (not ack tracking and
  not with the IP header which is what we have now).

f3ed235ba7 Tuning the format of the pretty-printed alarm summaries. 
Turns out the old format doesn't work well with the new scripts.

73d5643302 A new notice script that pretty-prints alarms in the summary email. 
It works already, but the actual pretty-printing is still missing.

f0b32b21ee weird.bro rewrite. 
- I want to test it for a short while before committing it to
  master just to make sure it is a sane modification.

3900d88e60 Field name change to notice framwork. $result -> $action 
- $result is renamed to $action to reflect changes to the notice framework
  since there is already another result-like field ($suppress_for) and
  there may be more in the future.

- Slipped in a change to add connection information to notice emails too.

0803df2e14 Changed communication option from listen_encrypted to listen_ssl. 
- Robin pointed out that SSL is providing authentication
  as well as encryption so listen_ssl is a more
  proper variable name.

6d67f7830d Added to the likely_server_ports set for protocols with analyzers.

  correct now.

- Updated BPF filter test since I added a few ports to IRC
  as well.

da9b8cc283 Modification to the Communication framework API. 
- Simplified the communication API and made it easier to change
  to encrypted connections by not having separate variables to
  define encrypted and unencrypted ports.

- Now, to enable listening without configuring nodes just
  load the frameworks/communication/listen script.

- If encrypted listening is desired set the following:
	redef Communication::listen_encrypted=T;

- Accompanying test updates.

5a04190ffe More adjustment to reduce Weird volumes. 
- New script extracted from weird.bro to implement the
  connection related "weird" data into an optionally
  loaded script.

- Adjusted the default notice tuning to stop ignoring
  the connection related weirds since they aren't loaded
  by default anymore.

aa9fdf38bb Clean up to cluster framework to make event handling clearer. 
- Fixed a bug where notices were being passed to proxies.
  This was a mistake and should greatly reduce load on
  many clusters.

- Cluster event regex variables renamed to:
  - Notice::manager2worker_events
  - Notice::manager2proxy_events
  - Notice::worker2manager_events
  - Notice::worker2proxy_events
  - Notice::proxy2manager_events
  - Notice::proxy2worker_events

- The default Notice::policy set is cleared for all cluster
  nodes except for managers to cause all default notice
  processing to occur on managers.  This should reduce load
  on workers slightly.

e6a3dbfb5d Fixed a bug in the notice framework.
