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

Netflow field definitions are now extracted to a bundled YAML file and also

types doesn't require a rebuild of Logstash.

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.
Removes unnecessary elsif

Allow host to be set from the original event

This seems to be possible with other input types, so I thought it would
make sense here as well. Maybe I'm missing something?
