Title: augmented the Rails 4 guides with links back to Github

asda @spastorino created a good [blog post](http://blog.wyeworks.com/2012/11/13/rails-4-compilation-links/), which compiled a lot of useful information regarding rails 4. I especially liked the links back to Github to read up on the topics.

* I added a list of plugin extractions
* I added a few missing important changes (HTML5 helpers, encrypted cookies, pg array support)
* I added Links back to Github PR for certain Changelog entries
