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
Might be good to bold + title case the bit that are "in" so:

`* **The Public Headers** - These are stripped for application targets, as they are only important to distribute the framework as code for compilation. The public headers also include the generated headers for public Swift symbols, e.g. `Alamofire-Swift.h`. 

( could Alamofire-Swift.h be linkable to one in the repo? )
