Cocoa Port:

- New feature: Audio files may now be used as audio generators for microphone input. Any Core Audio supported audio format may be used.
- New feature: A sine wave tone audio generator is now available as a microphone input.
- Fix bug where retrieving input device info from a CommandAttributes struct would retrieve garbage values if an object value was nil.
- Fix bug where editing input settings would immediately change the input device info state, instead of waiting for user confirmation as intended.
- Decouple the audio sample generation code from the microphone handling code.
- Do some code cleanup.
