Fix '@tags' not in log4j input
- bump lumberjack gem version
- bump lumberjack version again.
  This version of lumberjack has a 3x (average) performance increase vs
  the previous implementation in terms of event rates. On my
  workstation, the last release of logstash could do roughly 8000
  events/sec, where this commit peaks at 23000 events/sec
  (with a single lumberjack client connection).
- update filewatch which has a fix for LOGSTASH-881
Fixes #880 - Adds support for sending tags in gelf output

This adds tag support to the gelf output.

It adds a new option called ship_tags, set to true by default, when
sends all tags as a new field called _tags to GELF. Tags are converted
from an array to a comma separated list.
Updated CHANGELOG

Merge pull request #333 from jamtur01/gelftags
