update postfix queue example
Created symlink for /var/lib/logstash/logstash.jar

The puppet manifests expect it here. If you'd prefer that, i could also change it in the puppet manifests.
add sort filter
Add IPv6 grok pattern.

Rename IP pattern to IPV4 and add new IP pattern that matches either IPV6 or
IPV4 patterns.

IPV6 regex swiped from http://forums.intermapper.com/viewtopic.php?t=452
Include filter/output class name in skip/drop debug log messages

Bit distressing to see log messages like 'Skipping event' without seeing
*what* is skipping it!
- fix a duplicate 'message' field (overwrite it)
inputs: rabbitmq: fix optional exchange binding

Make hot_bunnies implementation behave the same as the bunny
implementation: optionally bind the input queue to the output exchange
if the "exchange" option is defined.  If it is not defined, some other
out-of-band process will need to setup the bindings.  Remove the
backward-compatibility reference, because this is actually a useful
feature to continue supporting.

an edge case
Use 'message' as the default field
- add tests to cover grok singles with duplicate field names
- fix an edge case where you have something that captures a few patterns
  to a named field, like (%{INT:foo}|%{WORD:foo}) and it only stores one
  and as a single value.
