Title: change field names to be in line with Logstash 1.2.x expectations

Renaming the fields used - these are the new names used by Lumberjack, which is as close to "authoritative" as we could get on what fields should be named.
This is definitely not backwards compatible - I'm open to finding ways to make it so, but at some point I think people will probably need to make the switch.
