Add a stub serverspec test to our acceptance tests
Don't run tests for the combo of Ruby 2.0.0 and Puppet 3.0.1

Puppet 3.0.1 does not support Ruby 2.0.0, see
http://docs.puppetlabs.com/puppet/latest/reference/release_notes.html
Try different line break syntax to be compatible with Ruby 1.8.7
Gem serverspec is required for :development, not :test
