Title: Optimizing all images used in the guides

Optimized all images from the official guides with http://imageoptim.com/, for an overview of the file changes in size see: https://gist.github.com/2629041

I went over each image used by the guides, and checked the diffs manually. These optimizations should be safe to use with the guide's design.

note: Originally I have created this pull request on the docrails project, these changes were not suited for that particular project (wherefore my apologies).
After a short conversation with fxn on twitter, I decided to continue this here on rails.
