Updated Plugin to iOS 8

Apple changed the way Keyboard Views are created and the App would crash when clicked in any input.

Now, Apple has the QuickType feature, and they added the order of the views. I fixed that by returning the proper list to iterate on the getKeyboardViews method.

Testing Devices:
iOS 8: iPhone 6, iPhone 5S and iPhone 4.
iOS 7: iPhone 4
iOS 6: Simulator
