Prove that there's an issue with media player audio.

- File format of files downloaded from GoogleVoice:
  MPEG ADTS, layer III,  v2.5,  32 kbps, 8 kHz, Monaural
- If we seek in that file before beginning playback, there is a very
  obvious triple/quadruple stutter.
- This adds a unit test that plays such a file after seeking, which
  clearly demonstratest the stutter on my variable speed library.
- This same test can be used to demonstrate the stutter with the regular
  MediaPlayer.

Other:
  - Also adds the correct ADD_VOICEMAIL permission, which was renamed
    earlier.
