Use 4560 (log4j default) as default port
Refactor netflow codec.

Netflow field definitions are now extracted to a bundled YAML file and also
introduces a new config directive to specify an additional YAML file that

TODO Work out how to get the YAML file added to the jar.
Add example YAML to documentation
Pull Netflow YAML file into the jar.
Update logstash.spec

Updated to version 1.3.2 and also added support for the ARM version of Fedora.
Correctly set RUBYLIB for JRuby.

Make sure the i18n gem is v0.6.6 or newer
because lib/logstash/runner.rb uses `I18n.enforce_available_locales=`
which isn't available until v0.6.6.
Fix `bin\logstash.bat deps` on Windows and add coaching for common bootstrapping problems.
Work around mutex lock in geoip ruby module. Doing it this way consumes slightly more memory but unblocks the threads when there is a high amount of concurrency against geoip lookups (eg, when you are processing web server logs).
