Posts found by their words

/api/v2/search now searches statuses by words for a signed-in persona, in
Mastodon's scope: what it wrote, boosted, favourited, bookmarked or was
named in, and public posts of authors who let themselves be indexed
(indexable, off by default). Newest first, only what the persona may see,
through a text index over the posts' words in every language alike.
