Fix convert to PNG mess

Automatically converting a damaged file to PNG and updating the archive
is fine as long as we're *in* the archive, but it totally messes things
up if we're browsing the file system.

So check if the image is in the archive path, and only then consider
auto-converting it. Also show a notice in the InfoItem if the file has
been converted.
