CocoaPods 0.36

Initial Draft for the blog post about the upcoming release.

#### TODOs
* [ ] Review, stylistic improvements, fix typos, …
* [ ] Add the assets
* [ ] Update **pygments.rb** to a version, which brings a lexer for Swift
> So this release goes along with probably one of the most drastic change set on the whole project, which makes no stop on CocoaPods itself, but also required similar changes to Xcodeproj as well.

I think I get the feeling behind this sentence. "This is the largest singular changeset to CocoaPods, as well as the other gems we use." if I'm correct, then I think this should go in the opening TLDR at the top, as it's a really cool intro stat.

I will make a comment up at the top around this.
