Suggestion: port gem mimemagic from Ruby for significant (and fully platform agnostic) MIME type coverage

[mistergibson]

I notice the unix and windows mime code is rather skeletal and incomplete. I want to suggest you simply port the mimemagic gem from Ruby to save time. It is very comprehensive in its coverage of mime types, has a byte-stream recognizer, and does filename extension recognition as well. In my Ruby code I have come to rely upon it and it has helped a lot.

Cheers,
