Return correct mimetype for MP2 files

[GoogleCodeExporter]

Mutagen 1.21 returns a mimetype of audio/mp3 for both MP2 and MP3. For example:

mutagen-inspect Audio_Promo_Night.mp2

identifies the file correctly but returns the wrong mimetype:

-- Audio_Promo_Night.mp2
- MPEG 1 layer 2, 128000 bps, 44100 Hz, 29.45 seconds (audio/mp3)

Two small commits in http://code.google.com/r/danieljames-mp2/source/list fix 
this for me with mutagen-inspect.

Sorry for the late response.

I'd prefer the attached fix, since MP3 handles all of MPEG.

Any thoughts?

Hi Christoph, this is a much better solution than my patch. The correct 
mimetype is returned even when the MP2 file has an incorrect or ambiguous 
extension:

('--', 'unknown-MFM0001-256kbps.mp2')
- MPEG 1 layer 2, 256000 bps, 44100 Hz, 257.16 seconds (audio/mp2)

('--', 'unknown-MFM0001-256kbps.mp3')
- MPEG 1 layer 2, 256000 bps, 44100 Hz, 257.16 seconds (audio/mp2)

('--', 'unknown-MFM0001-256kbps.mpeg')
- MPEG 1 layer 2, 256000 bps, 44100 Hz, 257.16 seconds (audio/mp2)

Thanks!
