Lets make it dead simple to add a new reference where the original URL is dead.

Proveit now features an Archive button next to URL fields, that fetches for the latest archive.org snapshot and shows the URL to the user. The user may then copy the URL and paste it in the relevant archive field. Pasting it automatically to the relevant archive field is not straightforward because the name of the field varies per-wiki and per-template, so doing so would require per-wiki and per-template configuration, which seems overkill.

Might be good to have a reminder for users to check the archive link, as there are quite a few error 404 or similar snapshots that don't really add anything new.

I have improved the UI and changed the success message to "Please test the archived URL before using it".
