Guts: use duct tape to make useradd feature list more useful
Add 3.1.1, 2.7.21, 2.6.18 references

All of these have an indirector reference copy-pasted from the previous version,
due to #19777.
Merge pull request #142 from jjulien/useradd_features

This page has been decomissioned and now points to an official puppet-docs
guide:

  http://docs.puppetlabs.com/guides/file_serving.html
