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
* **A Code Signature For The Whole Contents** -  This has to be (re-)calculated on embedding a framework into an application target, as the headers are stripped before.
