[Post] Add draft of CocoaPods 0.35 release post

The link to « [language-agnostic resolver integration suite](https://github.com/CocoaPods/Resolver-Integration-Specs) » leads to a repository whose `README.md` is empty. The reader won't understand why we are pointing him/her to this repo. Well I don't quite understand it either. We should at least provide some content in its `README.me` to explain what this repository is about.
