[ansel] Patch for user preference to show EXIF data

[Chuck Hagenbuch]

Quoting "Heath S. Hendrickson" <heath at outerspaceconsultants.com>:

> I added another user preference to allow a user to select whether they
> want to view the EXIF data automatically or not.

1. Please read docs/CODING_STANDARDS.
2. Please submit changes as unified diffs.
3. Please put diffs into text/plain attachments so that they are not butchered
by linewrapping.

Thanks,
