Disable multiline codec
Escapes character "_" in order to show properly on documentation.
Merge pull request #556 from leandromoreira/patch-2

Escapes character "_" in order to show properly on documentation.
- The plain codec splits by line, and filewatch emits blobs without
  newlines right now, so tack on a newline until filewatch gets
  refactored to emit blobs instead of lines.
- log the compiled code more readably
- clarify rbx issues indicating that I haven't really done any debugging
to figure out where the problem is.
- update changelog with todos
- remove unused require
- try to fix up require() debugger

implemented script to auto generate shipper configuration for PHP-FPM/MySQL/Redis
add prctl separately
Small fix for logstash/event.rb's sprintf method.

I found this with the riemann output - if you set it up with:
riemann_event => [ 'metric', 0 ]

Then the value gets sprintf'd, which utterly fails in this unquoted case, as 0
is a Fixnum, which doesn't have an index method.

This, we explicitly call .to_s in the sprintf method, to ensure that the
format is a string before call .index on it
