Removed troublesome cronjob that automatically adds the pe_mcollective
class to the default group every 2 minutes.  This should be reverted
once 2.8.1 is released.  More info:
http://projects.puppetlabs.com/issues/19230

Removed the centos64.pp file, since it no longer exists

Updated gitignore file

Added a second host that would run 2.6 for testing purposes
