Fix podspec

- The Offline subspec does not support OS X.

- Online sources are now duplicated in the Offline subspec.

- Cocoapods won’t let us target iOS 7 because we are using Swift and Cocoapods uses dynamic frameworks. Although the code should work on iOS 7 when used in source form (this is why the deployment target remains unchanged in Xcode), we set the deployment target to iOS 8 when using Cocoapods.
