new Thumbnail Managing Standard proposal

[Olivier]

Hi all,

Attached is a new version of the Thumbnail Managing Standard. I've discussed
this with Jens Finke, and we decided it is ready for comments, and perhaps
publication.

The major change is the addition of read-only 'local' thumbnail
repositories. For example a CD with images can include the thumbnails for
these images.

Please comment!

regards,
	Olivier Sessink
