Title: Add commands for changing voices for the speech functionality in OS X.

This PR add 3 new configuration commands that allow to change Betty's voice in OS X when text-to-speech is enabled.

```
betty list your voices
betty change your voice to Zarvox # or any other previously listed voice, no quotes needed
betty what is your voice
```

Refactoring or any other kind of suggestions are welcomed!
