add the puppetlabs/ntp module to the mix
Time fixes
added some docs/notes
added a ntpdate cronjob to the default training VM
add fundamentals::time by default
fix typo - bootstrap
Changed master.puppetlabs.vm to $::servername

Also removed it from being added by default, since that would mean
  not being able to classify it from the console and changing
  $offline to true as needed without editing manifests/init.pp.
