Fix Cocoapods support on OS X

Cocoapods apparently doesn’t allow subspecs of a given pod to have different deployment platforms. (At least, it doesn’t work with the current version 1.0 of Cocoapods.)

Since the offline core is not available on OS X, we have to resort to publishing two different pods:

- AlgoliaSearch-Client-Swift, corresponding to the Online subspec, supporting iOS and OS X
- AlgoliaSearch-Offline-Swift, corresponding to the Offline subspec, with a dependency on AlgoliaSearchOfflineCore, supporting only iOS

Refs #68.
