Add reduced version of GoodCityModern and the Blinkenlights post.

Note the use of `<span>` elements for each paragraph instead of a
single `<div>`.  From the Markdown syntax specs [1]:

  Note that Markdown formatting syntax is not processed within
  block-level HTML tags. E.g., you can’t use Markdown-style *emphasis*
  inside an HTML block.

  Unlike block-level HTML tags, Markdown syntax is processed within
  span-level tags.

I also had to add the `meta` directive to index.mdwn, because the
directive does not seem to affect pages through `inline`.  Possibly
and ikiwiki bug/limitation.
