debug msg when trying to split a non-string type
Merge pull request #421 from cosmok/mutate_add_debug

debug msg when trying to split a non-string type
- Add a sleep filter
- Use Stud::Task to more easily manage any exceptions from the Agent
runner
- Add experimental ruby filter
- Add example parsing the graphite carbon text protocol
- exit nonzero on configuration errors; this also has the intentional
effect of not barfing a stack trace on config errors.
- improve validation reporting
- check to_f and to_i conversions with :number validation
- Graphite input! :)
- include all fields by default (include_fields being empty is default,
so we want all by default!)
- add 'replay' mode to the sleep filter. This enables replaying of
events on a scale of the original event timeline. You can change
the speed by setting 'time' to a multiplier (2 == 2x faster, 0.5 == half
as fast)
- log when we sleep
- add elasticsearch input. Uses the 'scroll' rest api to walk through
  a given query's results.

Fixed class names in class 'end' tags. Only did inputs + filters. Outputs nearly all are missing the comment.
