Add dummy implementations to satisfy new IOBluetoothDeviceInquiryDelegate protocol in 10.8

The author of #2 and I have both found that the latest versions of Mac OS X (10.8.2 here, and 10.8.3 for him) have new required methods in the [IOBluetoothDeviceInquiryDelegate protocol][1]. I've added some no-op methods in order to satisfy the protocol and to allow LightBlue to continue.

Thanks for posting this updated version! It's been a big help.
