Support wildcards and globs in graphite targets. Check if any of the
values are above/below thresholds.
Use v.first.nil?
Add error handling for snmp checks
Only use begin..rescue block around connection and data collection
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)
Travis fixes
Swaped a negated if for an unless statement
Removed not so useful description
Added first version of PHP-FPM metrics plugin.
Fixed -n --name "varnish_name" option handling.
Add twemproxy to graphite plugin.
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.
