	* camel/camel-medium.c (camel_medium_class_init):
	new class. Will handle all sort of information media
	(Mime mail messages, Lotus Notes  mail messages,
	postit notes, faxes, who knows .... :)
	CamelMimePart will inherit from it.

	* camel/camel-mime-part.c (_set_disposition):
	(_set_description):
	description and disposition parameters are now const.


	* camel/gmime-content-field.c (gmime_content_field_free): added
	assertion code.

	* camel/providers/MH/camel-mh-folder.c (_get_message):
	uses buffered stream.

	* camel/camel-stream-buffered-fs.c:
	new stream to accelerate file ops.

Thanks to jwz, I've decided to add a level of abstraction to Camel.
In the future, it should be able to handle other mail systems, but
also non-mail information vehicles.

Enough for today. Roller time!
