Cleaned up and committed, thanks!

>From docs/TODO:

- Scan for embedded (EXIF) information at upload time, and store the
attributes in a database/categories backend. That way they can be
searchable, editable, added to, etc., and we don't lose them when/if
the image is edited or the format changes.

No, but this shouldn't have to involve preferences...
