check-beanstalkd: Fixes the types of W,C arguments.

Unless the default was used, the argument would be a string instead of a tuple
of numbers which wouldn't be comparable to a Fixnum lower in the code.
Added an option to allow users to set the comparison operator between the snmp data and the warning/critical threshold.
Make prefix optional.  Add graphite support ('flatten' hostnames)

Statsd extension: Need to append \n to metric batch before sending
Corrected the parsing of the use_ami_role setting from sns.json.
This statement
  settings['sns']['use_ami_role'] || true
doesn't work for {"use_ami_role":false} because false || true == true.
As a result, useAmiRole would always return true no matter what the
setting was in sns.json.
Introduced a nil check instead.
