fbe321eebf change exif names argh
change exif names again: we were storing under @title, but that's both
subject to i18n, and unlookupable in libexif

we now use @name, which is not subject to i18n and can be searched for
... this will break most code which expects certain exif tag names

also, when we update exif, allow any tag, not just updates to existing
tags, see:
