This should close #3482

Rebase required due to conflicts with other merged PRs.

Please test your changes. There is a missing comma in the SQL query.

store: unable to update integration record: pq: syntax error at or near "archiveorg_enabled"

Sigh, I thought that the rebase would be trivial, so I didn't bother testing this PR again, my bad.

FYI, there's a significant number of sources you can pull web page from. See web-archives extension selection: https://github.com/dessant/web-archives/wiki/Search-engines

You make archive.org hardcoded, which eliminates easy path to extend this further.

IMO, better way would be to have a selection of archive sources and have a generic interface implementing archive retrieval. Even if archive.org will be just only one for now.

That'll make it possible to pin source for a feed, for example. Or implement fallback mechanism of some sort.

I'm planning on adding more once this one is merged :)
