Add an HTML mode to posts, page intros and announcements

Markdown is the default and unchanged; the editor's new Format switch
stores the text as raw HTML instead, put on the blog exactly as written.
Like the custom HTML module it is unsanitised on purpose: the escape
hatch for embeds, scripts and inline styles that Markdown cannot express.

The source column keeps holding the text in both modes and a `format`
column says how to read it, so the public templates and the feed still
print the stored `*_html`. The dashboard preview of HTML goes into a
sandboxed iframe rather than the page, because a superadmin edits other
people's blogs and their markup must never run on the dashboard origin.
Search snippets of HTML posts are cut from a tag-stripped copy.
