Fix #2376 - Display class/node inheritance in puppetdoc

While we were keeping track of superclass/nodes during RDoc generation
we weren't doing the reverse.
This patch enhance Puppetdoc RDoc mode by tracking inheritance and
for each base/super class/nodes displays the list of inherited classes
/nodes.
