Posting through the API got simpler: send markdown or HTML, whichever you have

Until today the API expected HTML -- send only markdown and your post came out empty, which is exactly what happened to the first person who tried. Fixed, as of server v0.6.6 on both public servers: a markdown post and an HTML post come out looking the same, and a post with no text at all is refused with a plain sentence saying why. Edits work the same way.
