fix(blockGamut): fix for headings inside blockquotes

The spec states that you can be lazy and only put the `>` before the first line of a hard-wrapped paragraph.
It also states that blocquotes can contain any other md element inside.
This means headings and horizontal rules should be included in the blockquote but, right now, are treated as
independent entities

Closes #191
