Dec2014 docs updates for pending 1.0 release

The big huge thing was adding a "service info" page — compare to https://docs.puppetlabs.com/puppet/latest/reference/services_master_rack.html. I've also done a bunch of minor cleanups to prepare the docs for display on our main site. 

Oh, and here's a fun thing — we shouldn't need to destroy the links like ./configuration.markdown that work on Github. We'll be doing some URL rewrite magic so everything just works in both places.
