Extending plugin interface from CDVPlugin

There is an error currently for this plugin in iOS 8 where the following error occurs:

 <Error>: *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[CordovaDisableNSURLCache hasPendingOperation]: unrecognized selector sent to instance 0x14dc3060'

hasPendingOperation is defined in CDVPlugin but not in NSObject.
