Adding Playnomics Spec for version 1.1.0 of our new iOS SDK

Adding a specification for our new iOS SDK: http://github.com/playnomics/playnomics-ios.

This will replace the existing PlaynomicsSDK specifications which were submitted outside of our company and based on a now deprecated version of the SDK. We strongly encourage our users to migrate to the new SDK for it's new features and other awesomeness.
