Add example for dictionary_path
- revert rabbitmq plugin to the amqp plugin as in logstash v1.1.9
  The goal is to make rabbitmq function again as it was broken in
  v1.1.10. (LOGSTASH-1054)
- make 'update' set a field value if it exists but do nothing if not
- make 'replace' do what it should, which is replace a field (or create
  it if it doesn't exist).
- update changelog
- Prep for release.
- remove references to monolithic
- add comment explaining what 'jar' does
- fix bug in useragent (bad variable name)
- make tests run correctly to catch future jar issues fixed above.
- fix dumb typo
- fix failing tests caused by scoping problems and instance_eval
- run email tests, too
- prep for release
Fetch and pack kibana up into the jar
- add kibana runner
- only load elasticsearch jars and deps; prior to this, it was loading
  *all* jars found in vendor/**/ which would load ruby_http_parser.jar
  and cause http_parser to fail later... strangely..

  This only affected runs from git, not the jar releases.
- improved require() debugging
- dev build
- actually rsync it.
- no backend to select.
