LibMarkdown: Render lines to terminal instead of a single string

Browse source 
With this patch, the blocks in a markdown document render a vector of
lines. These lines get concatenated in Document::render_to_terminal, so
this does not change any external APIs of LibMarkdown.

This change makes it possible to indent individual lines in the rendered
markdown. So, rendering blockquotes in a similar way to code blocks :^)
