Implement archiving, stop updating indexes in the gadget
- Stop updating indexes in the gadget. It's simpler to just have the bot do it.
- If a wish has status=archived, put it only in the Archive index, not in the All, Recent or focus area index.
- I used "archive" instead of "archived" for page names since things go in an archive when they are archived.
- I used "Community Wishlist/Archive" instead of "Community Wishlist/Wishes/Archive" to avoid conflicting with the wish title prefix.
- In WishStoreUpdater, if there are no wish pages, avoid an exception.
- Fix typo dasboard -> dashboard
