Arbitrary localized columns for searching

[jnvsor]

Searching was requested in bug #7 which was closed for an unrelated question tacked on to the issue, but not being able to search is still an issue.

In order to make translated columns searchable they would need to be split out like the slug, instead of stored in the data json.

Since we already have a working mechanism for the slugs, how hard would it be to allow arbitrary columns to have their localized versions stored in separate columns instead of in the data json? From there all you need is a tweaked search query and you've got working multilingual search.
