Add support for the LineBlock element to writers

The following markup features are used to output the lines of the `LineBlock`
element:

  - AsciiDoc: a `[verse]` block,
  - ConTeXt: text surrounded by `\startlines` and `\endlines`,
  - HTML: `div` with an per-element style setting to interpret the content as
    pre-wrapped,
  - Markdown: line blocks if the `line_blocks` extension is enabled, a simple
    paragraph with hard linebreaks otherwise,
  - Org: VERSE block,
  - RST: a line block, and
  - all other formats: a paragraph, containing hard linebreaks between lines.

Custom lua writers should be updated to use the `LineBlock` element.
