 When looking for audio/video enclosures to add to new posts WP relies on
 the hosting server (for the media file) to provide a useful/correct mime
 type.  Some servers will provide generic types (like binary/octet-stream)
 instead of a more specific type.  A common case is Amazon S3, which
 defaults to binary/octet-stream.  Not having a specific mime type (like
 audio/mpeg instead of binary/octet-stream) will cause WP to miss what
 would other wise be a valid feed enclosure item.

 WP already has a list of common file extensions and their associated mime
 type in the get_allowed_mime_types() function.  We can compensate some
 what for these non-specific mime types by comparing the file extension
 with the list from get_allowed_mime_types().

 I've put together a simple patch that adds a look up loop to do_enclose(),
 if we find a mime type match based on the file extension it uses that
 instead of the type provided by the hosting server.
