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. 
Is this link incorrect or is it expected to not work from these markdown files?
